We’ve actually known since Google’s hilarious video this summer that plenty of normal people have absolutely no idea what a web browser really is, even though most use one on a daily basis. But today, Google has put together what can only be described as an extremely dumbed-down one minute video (below) and rudimentary website to attempt to explain to everyone once again exactly what a web browser is. And make no mistake, the undertone is clear: You should be using Chrome.

The web site consists of five parts: An area telling you what browser you are currently using, a place to show you the one-minute video, an area to show you a bit more about browsers and their performance benchmarks, an area to let you pick a new browser to try, and an area with tips and tricks for using a browser.

The video is much more subversive. While the first part is spent explaining what a web browser is not (not a computer, etc), by the end, Google throws out there that “the web browser is the most important piece of software on your computer.” And they continue, “so a faster web browser means that you’ll save time on every web page you open.” The hope there is that of course, people will look into what web browser is the fastest, and figure out its Chrome, and install it, since it is free to do so.

Of course, Google doesn’t bother to say that if you look up the fastest browser, find it to be Chrome, then try to install it on a Mac, you’ll be out of luck. Good luck trying to explain what Chromium builds are to these people, Google.

I all of a sudden don’t feel so bad having difficulty trying to explain to people what Google Wave is. And maybe now we know why Google actually is making Chrome OS: To stop having to explain to people what a damn browser is.

The top ad says it is linking to “Firefox ® OfficiaI Sitе” at the URL www.mozilla.com/firefox/. And that is indeed the official Mozilla Firefox site. But the link actually goes to the much more sinister firefox.mozilla-now.com, a site that dishonestly tries to get users to pay up to $2.50/month for an ongoing subscription to “24/7 Expert Customer Support” (a screenshot of the landing page is below). The credit card provider is based in the Netherlands.

Even advanced users who hover over the link won’t know what’s up before they click, due to Google’s ad redirect URL.

Most savvy Internet users will know this is a con as soon as visiting the site, but a all those middle-America Yahoo users may not know any better, particularly since they were just told it was the Firefox official site. It just goes to show that not even the stuff Google publishes can always be completely trusted.

Yoono, a nifty IE and Firefox plug-in that serves as both a social network aggregator and media hub, is launching a desktop version of their browser sidebar. Yoono basically aggregates and centralizes your online profiles, including IM tools like Windows Live Messenger, Google Talk and AIM as well as a wide variety of social networks such as Facebook, MySpace, Twitter, Flickr, Friendfeed and more. The startup also recently launched the ability to share pages and video/images in addition to real-time search capabilities powered by OneRiot.

The new desktop app, which is available for both Windows and Mac, has the same experience as the browser add-on except in a standalone product. The app is powered by Mozilla’s cross-platform xulrunner technology (the same technology Firefox is built upon), which is refreshing considering all of the Adobe AIR apps out there. Yoono says the decision to use xulrunner was made in light of its history as a Firefox add-on and the ease of porting.

Yoono has also released a new version of its Firefox plugin (which will be used in the desktop version), which integrates Twitter search and notifications when new results are available. The latest version also includes the ability to share web content simultaneously with MySpace. You could previously share to content with Facebook, Twitter and Friendfeed.

Additionally, Yoono has added stream filters to help manage your stream. This tool lets you hide individual users in your stream, across services such as Facebook or Twitter or both. You can also hide updates from a particular Facebook app. For example, you could hide Mafia Wars updates from any of your friends (very welcome!).

Does Yahoo consider IE8 safer than Firefox? Not if you visit the German Yahoo, which promotes Firefox 3.5 (a tragedy of a browser) by saying “Schneller und smarter: Der neue Firefox 3.5″ (translation: “Faster and smarter: The new Firefox 3.5″).

A year ago, when Yahoo and Microsoft were at war, Yahoo promoted Firefox to IE users.

So what browser is safest and fastest?

As Robin said, “Apparently, Yahoo recommends browsers based on what their latest business alliances are.”

My guess is the German staff haven’t received the memo yet. It’s IE, not Firefox, that’s the safest browser this week, guys. Get with the program.

As an aside, one Yahoo employee complained this morning that all Yahoo is doing is recommending IE users upgrade to IE8, and Firefox users upgrade to Firefox 3.5, which isn’t the case. After calling Robin an idiot and accusing him of not fact checking, he later apologized. We accept.

Update: Poor Yahoo Mexico doesn’t know what to do, so they promote both browsers in the header.

How ironic. About a year ago, following a failed acquisition attempt by Microsoft, Yahoo ran a very different recommendation from their front page, advising Internet Explorer users to switch to the “NEW safer, faster Firefox 3″ instead.

Apparently, Yahoo recommends browsers based on what their latest business alliances are. (update: or as Michael puts it, Apparently The Safest Browser Is Whoever Is Paying Yahoo The Most)

Maybe they should just develop and market their own browser and rid the confusion?

Twitter knows about the issue and says they’re working on it. And the odd thing is that the issue seems to come and go.

The worst part about this is that Twitter was actively promoting Firefox 3.5 downloads in July, and a lot of Twitter users are probably using it. This version of Firefox alone has around 4.5% market share already.

My apologies to Power Twitter, I originally (privately) accused them for the problems, and it looks like I was wrong.

Update: I’m testing Twitter with a download of the most recent alpha build of Firefox 3.7, and it doesn’t work either.

Marc Andreessen is backing a new browser company called RockMelt. Not much is known about RockMelt other than it is being designed by an all-star team (including software engineer Robert John Churchill from the Netscape days) and that it is tied into Facebook through Facebook Connect. Marshall Kirkpatrick at ReadWriteWeb has a screenshot of the sign-in page and speculates that RockMelt is in fact a Facebook browser. Miguel Helft at the NYT leans in that direction as well.  It kind of makes sense since Andreesen is on the board of Facebook, but I suspect it is only half the story.

A Facebook browser, however, is a good metaphor for thinking about how browsers, in general, need to change.  What would a Facebook browser look like? Well, to start with, you would be able to see updates from your friends on Facebook, share your own updates and media right from the browser, and perhaps IM with your friends through Facebook chat. While those set of features would be convenient, they are nothing revolutionary. Flock, which calls itself the social browser, already incorporates Facebook Connect (and Twitter and other social networks to boot), but it hasn’t taken off. And Facebook itself offers a toolbar for Firefox that lets you see notifications, search Facebook, and share links. There are plenty of other Firefox add-ons which incorporate Facebook features as well.

But the Facebook connection may just be the starting point for a much more ambitious piece of software. Andreesen said as much to the NYT in an interview earlier this year, which Helft quotes from in his article:

Mr. Andreessen suggested the new browser would be different, saying that most other browsers had not kept pace with the evolution of the Web, which had grown from an array of static Web pages into a network of complex Web sites and applications. “There are all kinds of things that you would do differently if you are building a browser from scratch,” Mr. Andreessen said.

What sorts of things is he talking about? Making the browser social appears to be at the top of the list. The first thing you do is connect to Facebook. But that could just be a building block for a social browser that handles Web apps in an entirely new way. The browser was built around the Web page metaphor, but increasingly the most interesting things happening on the Web do not necessarily exist on any one Web page. They exist in real time data streams (such as Facebook’s portable News Feed and Twitter) and in richer Webtop applications. A modern browser should be designed not only to surf the Web, but to manage your information streams and Web apps all in a seamless user interface.

Whether or not RockMelt is tackling this broader challenge, I don’t know. But I hope it is because we need to move the ball forward with a radical, yet accessible, new approach. Radical, yet accessible—that is the challenge. It must be radical enough to open up new, more efficient, avenues of information discovery, creation, and interaction. It must be a communications platform as well as a browsing platform.

The original browser model was one of consumption, of reading Web pages as if they were documents. Despite all the progress of the past decade, we are still stuck with that legacy to a large degree because it is built into our browsers. So what would a true social browser look like? Below is my own wish list of features (some of these are available as add-ons or in existing desktop clients, but there is an opportunity to unify them in one seamless experience):

• It would have multiple modes for browsing, search, following social data stream, and launching Web applications
• The home page would be a stream reader which brings together real time streams from across the Web (which Facebook now has with Friendfeed).
• IM, email, and public messages (status updates and Tweets) would be always accessible in the toolbar or a sidebar
• It would support a variety of Web apps which could be launched seamlessly within the browser without going to a Website and logging in.
• One-button access to sharing services of your choice (Flickr, Posterous, Youtube, Wordpress)
• Real-time search and alerts from across the Web (social stream, news, finance sites, sports sites, etc.)
• Support for Google Gears to give the browser offline capabilities as well as local caching and a light database for computing tasks

That’s just off the top of my head.  If you were redesigning the browser from scratch today, what would it look like?

Ever since the new Firefox 3.5 came out about a month ago, I’ve been using it as my main browser. Generally I am very happy with it. Pages load a lot faster than they did before, the plus-sign feature in tabs which launches a new one is a godsend, and I am very excited about the prospects for all of the open video technologies built into it. But there is one persistent bug that might push me to another browser: it keeps crashing on me.

This usually happens when I have too many tabs open (like 15 or 20, which is not unusual for me towards the end of the day). The whole thing will just freeze and I’ll have to force the browser to quit. When I relaunch I get a message like the one above, sheepishly saying, “Well, this is embarrassing.” Yes, it is embarrassing. A modern browser should be able to handle dozens of open tabs, and if there is a problem with one, it should be able to isolate it and allow you to carry with your business in the other tabs.

Without basic stability, none of the other great features or add-ons really matter much. Mozilla needs to fix this issue fast because Firefox 3.5 is already gaining a lot of traction. Net Applications has it at a 4.5 percent market share at the end of July, while StatCounter has it at 9.4 percent as of today. People are using this as their main browser, despite the beta label, and there are plenty of other powerful choices out there from Safari to Chrome to, yes, even IE8.

I realize that Firefox 3.5 is a just came out of beta, and to be fair, it has become slightly more stable over the past month (it was crashing every day in the beginning, now it is just every few days). I’ve been patiently waiting for the crashing to stop as Mozilla releases patches and updates. And I’m on a developer build, so maybe I’m just asking for crashes. But plenty of other people are complaining as well. Is Firefox 3.5 crashing for you?

And Mozilla is preparing for the big day with a new site (not live yet), called www.onebillionplusyou.com, which will go live on Monday. There, you’ll find information about the one billion downloads Firefox has seen, we’re told. When the browser hits the milestone, more information should also be available here.

Firefox has made a major dent in Internet Explorer’s marketshare over the past few years. The latest numbers put IE’s share just over 54%, while Firefox approaches 30%. That’s pretty incredible when you consider that just a few years ago, IE had over 90% marketshare.

This one billion number is obviously for all the versions of Firefox, since it was launched in 2002 (though the Firefox name officially took hold in 2004). The most recent version, 3.5, launched exactly a month ago. It zoomed past a million downloads very quickly, and had 5 million downloads after day one — a huge number, though not quite as huge as the Firefox 3.0 launch.

Update: Mozilla has just sent a note confirming that it will hit the milestone tomorrow:

It’s looking like Firefox will reach 1 billion downloads tomorrow (around 3:45 a.m. PT)! You can find out more here: http://www.spreadfirefox.com/fxbillion.

The new browser wars on on. More than a decade after Microsoft killed off Netscape with Internet Explorer, competition in the browser market has never been stronger. Just last week, Mozilla released Firefox 3.5, which has now been downloaded nearly 14 million times. Earlier in June, Apple released Safari 4. In March, Microsoft introduced Internet Explorer 8, and Google came out with a speedier beta of its Chrome browser.

Some early data is coming in showing relative market share and how fast people are upgrading. If you look at the chart above from Statcounter, it indicates that since March Internet Explorer has lost 11.4 percent market share to other browsers. That is the combined market share of IE8, IE7, and IE6. Certainly IE8 (the light blue line) has been growing strong since its release last March, capturing 16.7 percent of the market as of July 4. Those strong gains make up for most of the drop in IE7’s market share from 49.1 percent in March to 30.1 percent yesterday, indicating that Microsoft is doing a good job of getting existing IE7 users to upgrade at a steady pace. And in mid-June, IE8 finally surpassed IE6, which still stubbornly holds a 7.6 percent share. Add those three up, (IE6+IE7+IE8), however, and IE all together holds only a 54.4 percent market share versus the 65.8 percent combined share in March, 2009.

In just over three months, Internet Explorer has seen its overall market share erode by 11.4 percent. Where did that go? It went to Firefox, Safari, and Chrome. Nearly 5 percent of that, or about half, went to Firefox 3.0, which currently has 27.6 percent market share. That doesn’t count last week’s upgrade. See the dotted line just below the light blue IE8 line? That is a combined set of “other” browsers and appears to include Firefox 3.5, Safari 4, and Chrome 2.0.

If you look at a 30-day version of that same chart, it shows Safari 4 with 4 percent market share and Chrome with 3 percent market share. It doesn’t yet break out Firefox 3.5, but if you assume that makes up the bulk of the remaining dotted line which jumped to nearly pass IE6 in the past week, you can figure out more or less which browsers are taking share from Microsoft. (I’ve used data from the most recent daily chart in this post, but embedded the monthly chart below which has data as of June 30).

As I said, this is early data from one source. Net Applications, another commonly cited source for browser market share, is currently reviewing its June numbers, but I have a feeling they will show similar trends. (This Wikipedia page shows other browser market share sources, most of them haven’t been updated since March). It is difficult to make any firm conclusions at this point, since market share is shifting so rapidly as every major (and minor) browser tries to convince users to upgrade.

But we are in the midst of a major upgrade cycle simultaneously across IE, FireFox, and Safari (with the Chrome wild card thrown in). When all is said and done, we might see a major shake-up in market share and almost definitely will see leadership pass from IE7 to another browser. The question is will that be IE8 or Firefox? Whichever one wins, the good news is that IE6 is finally dying.

In the first 24 hours since its release yesterday, Firefox 3.5 has been downloaded more than 5 million times. (It took only a few hours to pass a million). That is certainly respectable, but doesn’t quite measure up to the mania that Firefox 3.0 set off last summer, when it achieved a “world record” 8.3 million downloads in a single day. Maybe we’ll have to wait for Firefox 4.0 to beat that record. But Firefox 3.5 might still beat the 11 million downloads Safari 4 got over its first three days of availability.

Who’s.among.us has some live usage stats from about 800,000 Internet surfers it is tracking. According to its data, it estimates that Firefox 3.5 already has gained about a 2.4 percent browser market share. Overall, it puts all versions of Firefox at 29 percent. That suggests close to 10 percent of Firefox users have already upgraded. It also puts Safari’s market share at only 2.5 percent, which seems low. (Other stats put it closer to 8 percent).

Looking at our own Google Analytics for TechCrunch, 28 percent of Firefox visitors are already on 3.5, but our readers are big Firefox fans—nearly half of all visitors use some version of Firefox, which is a much higher percentage than for most sites.

I’ve been playing around with the 3.5 release candidate for about a week. It is much zippier than 3.0, and I’m already addicted to the plus-sign feature on the tab bar which makes it easier to add tabs. And I love where it’s going with open video standards. It is also a bit crashy when I have too many tabs open, but that’s getting better. Some add-ons don’t yet work, but nothing crucial. Overall, it’s a much better product.

Mozilla today released Firefox 3.5 into the wild. Not surprisingly, it’s flying off the virtual shelves. And unlike when Mozilla released Firefox 3.0 last year, its servers are staying up and reliable, so the rate of downloads is pretty incredible. This site, run by Mozilla, shows the download stats for the new browser. Overall downloads are now approaching 1.3 million worldwide, with over 350,000 of those in the U.S. But even more amazing is the number of downloads occurring each second, it’s ranging from 59 to 95 right now. Again, that’s every second.

Outside of the U.S., the browser is moving quickly in Germany, France and the UK. The claim is that it’s much faster than the previous iterations of Firefox, and based on just a quick run-through of my favorite sites, I’d say that is in fact the case. Though, to be fair, it’s hard to know if that has something to do with the fact that just about all my browser plugins are not yet working with this version.

Not surprisingly, the emphasis on speed in this version of Firefox is on its JavaScript performance. Both Google’s Chrome and Apple’s Safari have been making headlines recently claiming to be the fastest browsers in this regard. As you can see in the SunSpider test chart below, it appears that Firefox has made huge strides since the slow days of Firefox 2, and has now more than doubled performance over even Firefox 3. As Apple recently touted in a press release: “Safari quickly loads HTML web pages more than three times faster than IE 8 and three times faster than Firefox 3.”

So how does 1.3 million downloads in a few hours stack up against its rivals? Well, the most recent browser to offer a major upgrade was Safari, which claimed 11 million downloads in 3 days. But those numbers are tricky because Apple includes Safari updates in its regular OS X software updates, so pretty much all OS X users were at least asked to upgrade after its launch. Still, Apple claimed that of the 11 million, some 6 million were users on Windows machines. And Firefox also pings users to do auto-updates when a new version is available.

Despite its launch hiccups, Firefox 3 set the Guinness World Record for software downloads last summer. In just 24 hours, over 8 million people downloaded the browser around the world. We’ll see how this version stacks up.

You can watch the live-updating chart and map for Firefox 3.5 downloads here.

The site is simply a Google Map zoomed out to a certain point. If you zoom in enough, you’ll find a surprise. The developer took exception to Microsoft calling Firefox “old” on its site. That is a bit odd since IE is much older than Firefox.

Mike Beltzner, the director of Firefox, was in New York City today and dropped by my office to talk about Firefox 3.5, which is now officially being rolled out as a “preview” version (a very stable beta) to everyone using the current 3.5 beta. Firefox 3.5 is supposedly much faster than earlier versions, which is always a good thing. Honestly, the nanosecond speed differences between most of today’s latest browsers is becoming hard to detect. Three features of Firefox 3.5 which stand out for me are: 1) its embrace of open-source video standards, 2) its geo-location capabilities, and 3) support for downloadable fonts and other graphic tricks.

In the video above, Beltzner demos some of the new video and graphics capabilities of Firefox 3.5. Built into the browser is a video player based on the open-source video formats Ogg Vorbis and Theora. The video player supports HTML5, which means that links and other interactive elements can easily be placed inside videos. The demo page Beltzner shows in the video can be found here (but the effects only work if you are looking at it in Firefox 3.5). Being able to treat the content inside videos like Web pages opens up a whole new world of possibilities for Web video. Already, DailyMotion offers all of its videos in the Ogg Theora format. If this takes off, Flash video could be come history.

Look closely at what Beltzner is showing off in the video, because you can’t do any of that with Flash.

Update: There is a lot of great debate in the comments about whether or not you can do this stuff in Flash. Technically, you can, but the only examples I’ve seen are where the entire page is done in Flash or a proprietary overlay is being used. The videos in the demo all sit within regular Web pages and are written in HTML5. What is interesting in my mind about the Ogg Vorbis format is that it makes videos programmable. Videos today are still for the most part siloed off from the rest of the Web in their Flash players as a separate experience. It is time to break down those walls.

Mozilla has unveiled a new project from its Labs division called Jetpack that gives us a taste of how Firefox might begin extending web functionality in years to come. While the project is still quite early in development, it seems to be taking the form of a streamlined extension system, allowing web developers to introduce new features to the Firefox browser using web-based tools and requiring only a minimal amount of effort on the user’s part.

Firefox extensions have long been one of the best parts of the browser, allowing users to add and remove features to suit their needs. But while the user experience of installing these has been relatively straightforward, it still requires a browser reboot, which can be frustrating when you’re in the middle of something. With Jetpack, this isn’t an issue – you click install and you’re done, with the new widget or application installed a few seconds later.

Jetpack is being described as “an exploration in using Web technologies to enhance the browser (e.g. HTML, CSS and Javascript), with the goal of allowing anyone who can build a Web site to participate in making the Web a better place to work, communicate and play.” In other words, if you know how to develop for the web, you should be able to build a Jetpack app. Developers can write code using Mozilla’s web-based Bespin environment and the popular Firebug extension. For an idea of how easy it is to build these applications, check out the video below.

At this point there aren’t many demo apps available, but you can try them out for yourself by going to the Jetpack homepage and installing the Jetpack 0.1 extension (you’ll have to reboot your browser to get it working). From there you can find demos here and here, with available applications including a weather forecaster, Delicious Notifier, and an Ad blocker (there’s also an app that will mix up the images seen in your open browser tabs, if you’re looking for something truly useless).

Because Jetpack is still in very early stages it’s tough to tell just how powerful it will eventually become, and if it could ever replace the current extension model. Looking beyond traditional extensions, the new project could potentially allow trusted websites to customize the browser experience on a site-by-site basis, which could prove quite useful (or annoying, depending how it works out).

After the slightly shaky launch of their ultra-early milestone release, Mozilla is back with more Fennec (otherwise known as “Firefox Mobile”) goodness. This morning, the company began distributing Alpha 1 of Fennec for Windows Mobile. As with all Alphas, this release is by no means intended for every day use by the general public, but it gives us a sneak peak at what’s to come.

Earlier tonight we received a tip with the screenshots below. As you can see, Google Finance has a brand new interface when browsed to with Chrome versus in Internet Explorer and also Firefox (not pictured). It would seem that Google may be checking for the Chrome user agent and giving those users a glimpse at this new version of Google Finance.

Our tipster called it “lame” that Google was only offering the new version of the site to Chrome users. But there is, of course, nothing wrong with Google doing this — provided that it doesn’t mean to permanently offer different (meaning better) versions of sites to only those users using Chrome. But that seems very unlikely. Instead, Google is probably just testing some new features out to a small set of users, just as a lot of other sites do throughout the web.

After it was launched last year, Chrome caused a bit of controversy on the web because of Google’s previously strong ties to Mozilla (makers of the Firefox browser). Some were quick to jump to the conclusion that Google entering the browser wars meant that it would specially tailor sites for its own browser and neglect all the others. But Google’s prominent position on the web — particularly with web advertising — pretty much ensures that it has to play nice with all web browsers. Or at least those not named Internet Explorer 6.

That’s a small, but useful feature, but the ramifications of this move are potentially much large. This adds location capabilities to the millions of people who have Google Toolbar installed. You may be thinking that a lot of those users with the latest version of Firefox already had it — but this feature is for Internet Explorer only right now. That, combined with Mozilla’s use of its Geode location plug-in (which again, is built into the latest version of Firefox), puts location on a good percentage of browsers in the world.

And while it doesn’t mention it, that’s important for Google’s own larger purposes. Its recently launched Latitude location-based network is only useful if it can automatically update your location, or make it really easy to do. Up until now, it has been a pain on a computer.

But there are other big things Google could do with location information — such as serve you location-based ads. There are other companies working in that field, but you can bet Google wants to get out in front of them and lead the charge. And with its own toolbar to get your location, it could potentially do that. It also promises the ability to serve up location-based search results with feature.

Google has been been working on location for a little while in the mobile space, but most users are still experiencing the web first and foremost through regular computer browsers. Google’s toolbar pulls location data from both IP addresses and nearby Wi-Fi access points — since most computers don’t have GPS built-in.

Much like it does with Gmail, Google added a “Labs” area to Google Toolbar today, to test this new feature. It also has a new, simple Chinese version of the Toolbar in this Labs area. Both are IE-only for right now, as I mentioned.

Today, Mozilla Labs released the 0.3 version of Weave, its project that syncs multiple browsers in the cloud. Weave lets users sync their bookmarks, tabs, passwords, and histories in the cloud across Firefox browsers on different computers. With today’s release, you can also sync with Fennec, Firefox’s mobile browser, which unfortunately right now only works on one kind of phone: a Nokia N810 Internet Tablet. Yeah, I don’t have one of those either.

But the idea of syncing your browsers is a powerful one for anyone who uses more than one computing device on a regular basis. Originally launched in December, 2007, Weave is now faster and more reliable. In other words, now it actually works (or so I’m told).

The one thing Weave doesn’t sync is all of your add-ons. But that is planned for a future release.

Mozilla Labs is debuting new personas today – extensions that add lightweight themed skins to your Firefox browser – enabling you to personalize your user experience according to your mood without interrupting your browsing sessions. The Personas for Firefox add-on was first introduced in late 2007, but has now expanded to include hundreds of artist-created designs in a variety of categories, according to a blog post announcing the new sets.

I like custom skins / themes and the fact that Mozilla is taking steps to make it easier for people to adjust the look and feel of their browser according to their mood, but somehow the announcement made me cringe a little (much like this Labs experiment did). I would rather see Mozilla focus on improving the speed and usability of its browser than offering its users ways to add eye candy, particularly now that the browser wars are heating up again. Firefox needs more innovation, not decoration. But then that’s just me. Some people love eye candy more than speed.

Mozilla Labs is experimenting with a design for a new tabs page in the Firefox browser that will show a circle of the top sites you visit that is reminiscent of the circle of friends design you see on many mobile phones. (Except, who needs friends, when you’ve got the Internet?) When you open a new tab, instead of a blank page, you would see a watermark of icons representing the eight or so sites you visit most often. By mousing over the circles, the the tab page would fade into the actual links.

This is just a concept design, but using that blank page when a new tab opens up makes sense. Aza Raskin of Mozilla Labs calls the watermark a”cognitive shield” because it is supposed to protect users from the clutter of all the links unless they explicitly mouse over the watermark. Also, it doesn’t appear if you start typing something into the address bar. He says he is considering making the circles themselves clickable, which would be more intuitive and eliminate a step. Giving users the ability to customize which sites show up in the circle would also be helpful.

The add-on only works on the development build of Firefox 3.1 right now, and may or may not find its way into a future general release.

The mobile version of the Firefox browser, Fennec, is now officially in beta. It works only on the Nokia N810 Internet Tablet, but developers can also download it onto their computers. The Fennec browser is designed to make maximum use of the limited screen space available on mobile phones and tries to do everything possible to minimize typing.

It incorporates the Firefox “awesome bar,” which acts as both navigation and search bar. Start typing in a URL or search term and it auto-suggests web pages based on your past Web surfing habits. Various searches, including Google, Yahoo Answers, and Wikipedia, are one click away via links at the bottom. The browser also remembers all your passwords, just like Firefox. It supports Flash. And add-ons can be created for the mobile browser.

The user interface takes some zooming and panning concepts which were previously previewed by Mozilla Labs. Each Web page expands to fill the entire screen, but moving the page to the side reveals different controls, including bookmarks, back and forward buttons, tabs, and different tools.

We’ve seen what competition has done for browsers on the PC. Today, Firefox, Safari, Chrome, and IE are all trying to leapfrog one another (well, at least the first three are). Efforts like Fennec, mobile Safari for the iPhone, the Android Web browser, Opera Mini, Skyfire, and others are injecting the same healthy competition into mobile browsers. I can’t wait to be able to try out Fennec on my mobile phone (if Apple or Google let me).

Below is a video demo by Madhava Enros, who is in charge of designing the interface for Fennec.

The event is timely. There has never been such robust competition in the browser space. Google recently brought Chrome out of beta, and Microsoft’s GM of Internet Explorer Dean Hachamovitch told me earlier today that the Release Candidate of Internet Explorer 8 would be released in the next two weeks.

Notably absent from the panel was Apple, although their Safari browser was brought up repeatedly as an important mobile platform, and Safari’s underlying Webkit javascript engine was also praised as innovative.

Most of the panel discussion focused on the browser ecosystem, including add-ons, standards compliance and security. The panelists noted that web developers have a harder time today than a few years ago because they have to build for more than one browser. But as Firefox and others have gained market share, competition has sped feature advances, accelerating the development and evolution of javascript and other languages and standards. Krogh from Opera noted that the next big battleground is mobile.

An audience question asked each of the panelists to describe the essence of each browser. The responses were varied. Microsoft’s Hachamovitch said his team starts with looking at what the user wants and building from there (and pointed to IE 8’s impressive feature list). Krogh from Opera said they wanted to supply a standards compliant browser for literally any Internet connected device. Google’s Pichal said speed (of javascript) was their primary goal (Hachamovitch then dubbed him “Mr. Speed” in a later comment). Mozilla’s Shaver said Firefox was about “putting the web first,” and creating a standards-compliant browser in as many languages as possible to ensure that no one was left out of the Internet.

Hachmovitch also confirmed that Microsoft has no current plans to build Linux or Mac versions of Internet Explorer. Google’s Pichal confirmed that Chrome for Mac was coming “very soon.”

Crunch Network: CrunchGear drool over the sexiest new gadgets and hardware.

In other Mozilla news, Firefox and other Mozilla products hit a major milestone today with the one billionth download of add-on software for the browser. That feat took three and half years.

Many of those downloads are never used more than once or twice, of course. But there is no doubt about it that Firefox is major software platform. Just look at StumbleUpon, it was built on top of Firefox.

What is atop the current list of most popular add-ons? Adblock Plus, followed by a bunch of download tools. And let’s not forget Greasemonkey at No. 9, which is it’s own Web development platform.
