To those using Google Chrome on Linux, extensions are enabled on the beta channel. And for those using Google Chrome for Mac, hang tight — we’re working on bringing extensions, bookmark sync and more to the beta soon.

If you’re on Windows, you can either wait to be updated to the new build automatically over the course of the next week, or you can manually upgrade if you want to get your hands on the new features right away.

Once you’ve got the new build, you can head over to Google Chrome Extensions to start extending your browser.  Or you can head on over to the Google Chrome Blog to find out more about what’s included in the new build.

Head on over to Air Mozilla to follow along with the release day proceedings.

Despite the fact that Firefox 3.6 RC1 was released on schedule yesterday, it has received very little attention from the usual official outlets, as far as I can tell.  For example, there is no mention of the new release candidate on the main Firefox page, and there has been no mention of the release via Firefox’s Twitter account.

Nevertheless, the RC1 build looks official, and the following are some of its key features and changes:

• Changes have been made to the way third party software integrates with Firefox in an attempt to avoid crashes.
• Nearly 100 bugs have been fixed since the last beta build to improve stability, performance, etc.
• JavaScript can now be loaded asynchronously, another performance boost.
• Improved DOM, CSS and HTML5 support.

If you decide to give Firefox 3.6 RC1 a spin, feel free to share your thoughts on the new release here in comments.

Update: I should clarify that the RC1 build is at least mentioned on the beta releases page.

emoko is a web browser just like FireFox or Internet Explorer, with one big difference  -  emoko is built using video game technology.

The browser apparently renders pages in a “3D world,” and users’ avatars in that 3D world can interact (via text and voice chat, or drawing on the page) with one another, as long as they are visiting the same web page.  The version at the time of writing is version 0.9.6225, and it is the second major update according to the browser’s website.

The following video demonstrates emoko’s vision of how the browser works:

Now that we’ve seen the video, I have to admit that I’ve actually installed and played around with emoko a bit.  Unfortunately, my experience wasn’t anything like what you see in the video.  The browser felt more like a Java app to me than it did a video game.  Even on my fairly powerful computer, things felt a bit slow and jittery.  If it’s possible to tilt web pages, create avatars and find other users in emoko, I couldn’t figure out how to do it. The best I could do is get a feel for the interface, which in itself is a bit different than what is offered up in the video:

Don’t let me be the judge, though.  If you’re into trying new things, give emoko a spin yourself and definitely let me know if you have a different experience than I did.  Regardless, it’s good to see people thinking outside of the box with web browser development.  This one may just be a little too far out of the box for my liking.

General

• This one is pretty funny, but maybe wouldn’t be as funny if it was true:  someone filed a Firefox bug claiming installing Firefox disabled his or her IE8 add-ons.
• WebKit received one of InfoWorld’s 2010 Technology of the Year awards for being a “tool for creating cross-platform smartphone development,” whatever that means.
• Yahoo! Answers, which is one of the most useless sites on the Internet, in my opinion, runs the gamut in attempting to answer the question “which language should I use to create a web browser?“
• Harry Parsonage went to great lengths to write a “forensics” paper on how privacy can be put at risk by various web browsers’ session restore feature.
• If you’re planning on attending MIX10 in March, Paul Scarpa of Spry Hive Industries is hoping to talk about the past, present and future of web browsers.  You’ll need to vote, though, to make that happen.

Chrome

• An article at Beet.TV claims that Google Chrome has reached 40 million active users worldwide since it’s initial beta release in September of 2008.
• Jim Lynch of ExtremeTech talks about why he switched from Firefox to Chrome on Mac.
• Dwight Silverman is using Chrome on Mac, too, and got pretty excited when a bookmark manager showed up in his build.
• If you’re a Chrome fan and an Ubuntu fan, you may like some of these Ubuntu themes for Google Chrome.
• Chrome’s Dev Channel was updated to version 4.0.288.1 yesterday across all platforms.  TechCrunch points out that the key features are those that showed up for the Mac platform:  bookmark syncing, the new “pin tab” feature, and most importantly, extensions.
• Unlike Yahoo! Answers, Stack Overflow provides a platform at which smart people can provide smart answers, such as this explanation of the difference between the browser process, the render processes and plug-ins in Chrome.

Fennec

• In a blog post that announces his transition from working on Fennec back to the desktop version of Firefox, Gavin Sharp also reveals how developing for Fennec was different than developing for Firefox, and introduces us to a few of the other major contributors to the new mobile browser.

Firefox

• John Lilly tweets about a theme/add-on combination that gives “glimpses of [Firefox] 4.0.”
• John Slater, Mozilla’s Creative Director, vows that Firefox marketing won’t go the Taco Bell route.
• Download Squad reports that Firefox 3.7 is showing some progress with its Windows 7 shell integration.
• Initial tests show that forthcoming multi-processor support in Firefox leads to a 3x speedup in JavaScript performance, but even that is still 50% slower than Google Chrome’s performance using the same test.

Internet Explorer

• Microsoft’s announcement that it had submitted a request to join the SVG Working Group sparked commentary from SitePoint and The Industry Standard.

Opera

• As you probably heard, Opera announced a new CEO this week.
• Opera is planning on releasing a browser beta for Windows CE and looking to find other niches after suffering losses of around $2 million during the last quarter.

The Minor Players

• “Digia @Web is a modern, fully finger touch controllable, web browser for mobile. @Web is currently available for S60 5th Edition and Maemo mobile devices free of charge.”  Techie Buzz has a review, which includes a screenshot.
• SRWare Iron Browser, which was mentioned here last month, has been reviewed, along with screenshots, over at GadgetMix.
• China is making some big investments in free software which could end up benefiting Maxthon.
• Flock 2.5.6 was released this week, fixing some integration issues with Flickr and Twitter.
• Reports from CES say that Ford has developed its own Web browser, which can be operated only while the car is parked (there’s more on the safety implications of related innovations in The New York Times today).  Left Lane reports that Ford’s browser is WebKit-based.
• This review of the Orca browser has plenty of screenshots for anyone who’s curious about the browser.
• Honza Pokorny, who you can follow on Twitter, has created his own browser, appropriately named Honza’s Browser, which you can try out on Linux or Windows.  He has also made the source code available.

No it’s not available yet. What you are seeing is the first candidate build of RC1…very very close but not quite there. It doesn’t help Mozilla either to point to direct FTP links instead of the mirrored links (HTTP) that will be published when it is finally released.

You are of course free to install the candidate builds if you’d like, but you won’t be using the actual RC1 build unless things go very smoothly with the build and there isn’t a need for another candidate.  That being said, as I pointed out to start this post, the actual RC1 build is expected to be announced on Friday, so you won’t have to wait very long to get the real deal either way.

I’m not sure what’s more surprising, how large IE is at its most-minimized state, or how small Chrome is.

You can read more about the differences over at Softpedia.

General

• In addition to needing an editor (”sometimes you a specialist”), Macworld may need to take a look at the latest browser market share figures.  They mention Chrome almost in passing while covering what some of the alternative browsers do better than Firefox and Safari.
• At a WebKit hackfest recently, some improvements were made to context menu handling, including the ability to hold the CTRL key while right-clicking to see the default context menu instead of any custom context menu provided by the current website.  Additionally, some include- and linking-related improvements were made to decrease the overall WebCore build time, which should come as good news to those 80 active WebKit committers.
• Avencius has some interesting thoughts on the competition between Mozilla’s Firefox and Google’s Chrome and suggests that, despite their lead in browser market share, the Mozilla folks should be worried.
• Some videos from Add-on-Con feature representatives for Chrome, Firefox and Safari and delve into topics such as browser security and mobile add-ons (via Dan Moore).
• Royal Pingdom takes a look at what 2010 has in store for the browsersphere.

Chrome

• In a LinuxCrunch review of the Linux version of Chrome (via Slashdot), it is touted as being “stable and fast,” but downsides such as lacking extension and RSS support are mentioned as well.  Additionally, there’s an interesting note about a KDE-related bug that Google has opted not to fix.

Firefox

• An article at TG Daily (via Digg) calls Firefox “clunky-looking” and says that the news Firefox 4 may not ship until 2011 “comes as some embarrassment for Mozilla.”  It goes even further to claim that Microsoft will now have a “clear advantage” over Mozilla and “bit-players” Chrome and Safari.
• An RC1 build of Fennec, the mobile version of Firefox covered here recently, was released tonight.
• You can get a feel for some of Mozilla’s plans for Firefox in the coming year over at Mozilla Links.

Internet Explorer

• Tweak Internet Explorer with IE Tweaker.
• One Betanews reader wants Microsoft to “release [an] HTML5 and CCS3 compliant IE9 by June with a radically new UI.”
• FavBrowser.com points us to some videos from IE9’s JavaScript engine team, namely John Montgomery, Steve Lucco and Shanku Niyogi.

Opera

• In its coverage of Opera’s added support for CSS3 Transitions and 2D Transforms in the pre-alpha build of Opera 10.5, CSS3 . Info mentions that “Opera is the first browser to offer support for Backgrounds and Borders without the need for a vendor prefix, with Firefox and Safari still requiring ‘-moz’ and ‘-webkit’ [respectively].”
• With the pre-alpha release of Opera 10.5, Anne van Kesteren says “we are getting a little better at this iteration stuff.”
• A couple of articles (via Slashdot), Opera 10.50 Unveiled: Opera Is Once Again the Fastest Browser on Earth and Opera 10.5’s new Carakan Javascript engine is fast – Google Chrome fast, go into detail about the impressive performance of Opera’s new Carakan JavaScript engine (which I’ve mentioned here a few times in the past).
• True to form, Opera Watch has a solid rundown on Opera 10.5 pre-alpha as well.
• In reporting on Opera’s State of the Mobile Web report from November, TechCrunch relays that Russia is the top country for Opera Mini usage, but that usage is really growing in Asia and Africa.
• Even though I think it’s a cool feature (which admittedly takes some getting used to), FavBrowser.com lends a hand to those who want to turn off Opera 10.5’s tab thumbnails in Windows 7 (I’m sure this approach works for Safari as well).
• The Opera Core Concerns blog provides some details on Opera’s native support for JSON, including performance comparisons against the other main browsers.
• In Carakan Revisited, improvements made to the Carakan JavaScript engine over the previous Furthark engine are discussed, mainly focusing on garbage collection and caching.  The post also touches on some of the plans for future improvements.

Minor Players

• SeaMonkey 2.0.1 was released as a security update this month.
• Now that Avant has been listed as one of the browsers to appear on Microsoft’s browser ballot screen, they need translation help.
• One Maxthon user thinks the browser is so cute that there should be a Windows 7 theme based on it.

There’s a lot more to cover, but that should hold you over until 2010.

Happy New Year, everyone.

Many computer programs are built using previous versions, or related code, but V8 was started from scratch – a blank slate. When I meet [Kasper] Lund later in my Denmark trip, he takes great delight in underscoring this fact: “It’s the purest form of coding there is.” [Lars] Bak clearly agrees – as Lund speaks, he can’t stop smiling.

Beyond detailing the story behind v8’s development in Denmark, the article gives a personal glimpse at its key creator, something his Wikipedia article doesn’t quite achieve.

If you’re interested in the developers behind the browsers or browser-related technology you probably take for granted on a daily basis, I’d definitely give the well-written The genius behind Google’s browser a read.

Fennec, which is currently at version 1.0 alpha 1, or also referred to as M9 (a user experience alpha),  can be installed on Windows, Linux and Mac, in addition to its intended target, the Nokia N810 Internet Tablet.  To do so, simply grab the zip file or distributable associated with your OS.

I installed Fennec on Windows 7 to check it out, and the simulation works pretty well.  You can see how pages are rendered according to the smaller screen size, and you can also get a feel for how close the rendering of the page is to what you see in your normal desktop browser.  One of the things that stood out in the aforementioned YouTube video was the fact that all of the controls are hidden off to the sides of the page.  You simply “swipe” left or right to access the currently open tabs and navigation/settings, respectively.

The following is a look at Browsersphere loaded up in Fennec:

And here’s a look at ESPN.com loaded with the currently open tabs displayed off to the left:

And finally, here’s a look at the Fennec release notes page with the navigation and settings icons off to the right:

Obviously, you can’t get the best feel for what Fennec will feel like running on its intended hardware by running it on a dekstop OS, but you get a general idea for the layout of the controls, the way the pages render, etc.  Overall, I got a good impression from my quick look at Fennec, and it sounds like others have been impressed as well.

If you’re as curious as I was about how Fennec compares to some of the other mobile browsers out there, I’d recommend installing it on your desktop computer and giving it a try for yourself.

In Chrome is not an Internet Browser and not open, but closed to the Internet’s Domain Name System, Scott Cleland, a self-proclaimed “prescient analyst,” claims that Chrome is “a gateway to Google’s datacenter to browse Google’s mirror copy of the Internet and track the user’s every movement.”  However, the two most incredible claims in the article are as follows:

• “Google’s Chrome browser effectively eliminates the Internet’s Domain Name System (DNS) address bar where a user can directly go to [a] URL.”
• “When one puts a URL, www.brand.com, into Google’s OmniBox search bar they do not go where they asked to go but to Google’s results page where Google can advertise against that brand without sharing the ad revenues with that brand, and where Google can offer competitors an opportunity to divert the user from their requested destination and to a competitor’s destination.”

The claims about Google’s “mirror copy” and bypassing the Internet Domain Name System are discredited point blank in a post from The Chromium Blog titled DNS Prefetching (or Pre-Resolving), which states “Google Chrome resolves domain names…using your computer’s normal DNS resolution mechanism; no connection to Google is used.”

That second bullet point, though, is the most easily discredited.  If you launch Chrome and type “www.starbucks.com” into the OmniBox, you are taken to www.starbucks.com.  You aren’t taken to a search results page and certainly don’t see any competitors offering their services along the way.  If you type only “starbucks” into the OmniBox, that’s a somewhat different story, but the article is making its claim about URLs, which is just flat out wrong.

Perhaps the most concerning fact among all these non-facts is that Scott Cleland is a consultant to Fortune 500 companies and an advisor to Congress! His bio states, “eight different Congressional subcommittees have sought Cleland’s expert testimony.”

He might as well have titled his article “Chrome bypasses the series of tubes.”

Having had those experiences in the past helps me appreciate even more the fact that the Chromium community has been publicly exposing details about the “guts” of Chromium in several tech talks posted over at the Chromium Blog.  The tech talks have been archived in video form on YouTube so that anyone interested in the details of Chromium development can find out more about what’s involved.

One video features Darin Fisher, who used to work for Mozilla, talking about The Chromium WebKit API.  In another, Pam Greene covers Chromium WebKit Layout Tests.  In another, Brett Wilson discusses Painting in Chromium.  Last but not least, Eric Seidel, who has worked on both Safari and Chrome, goes in-depth about Rendering in WebKit.

That last video is probably the most interesting to me, simply because it deals with the rendering engine and also unveils a few interesting facts.  For instance, WebKit is made up of almost 2 million lines of code and is developed by about 80 active committers, of which about half work for Google.

If you’re interested in how web browsers are tested, how HTML source gets transformed into what you see on a web page, etc., you’d be doing yourself a favor by checking out the Chromium tech talks.

• Maxthon reached the 300 million download milestone on November 28th.
• Skyfire Mobile Browser 1.5 was released last week with improvements made to their video support.  You can see a short video explaining the new improvements on Vimeo.

For more on the stipulations of the deal, be sure to read the coverage from The New York Times (via @MaxthonNews).

Rather than review the browser again, now that it’s matured quite a bit, I’ll do one better and share this YouTube video with you, which does a good job of showing off the UI, some of the important features, etc.:

If you’re interested in keeping tabs on what the Wyzo folks are up to, you can follow them on Twitter: @wyzo.  I’ve also added them to @Browsersphere’s list of web browsers.

As a follow-up to publicizing the @Browsersphere account on Twitter, I’ve created a new Twitter list for following all of the major web browser vendors:

@Browsersphere/web-browsers

The Bad News

Unfortunately, it looks like Safari is not represented officially on Twitter.  What’s up with that?

And no, I don’t consider @AppleSafari an official account:

Ironically enough, Browsersphere has been neglecting the browsersphere a little like Microsoft neglected Internet Explorer earlier this decade.  After all, my last post was way back in June.  However, unlike Microsoft, it isn’t the competition that has jolted this site back to life.  On the contrary, sites like Avencius and Twitter accounts like @AltBrowser have actually made me feel a little bit better about the whole ordeal, knowing that at least someone is out there covering the browsersphere in my absence.  Truth is, the site went dark out of pure laziness on my part.  Well, that and the fact that I’ve been pretty consumed by another project.  Nevertheless, I’m back, and after catching up a bit on what’s been going on, my first order of business is to share a little bit about what’s been tweeted in the browsersphere lately.  So let’s get to it.

• @UKTJPR wonders if anyone is willing to give up their web browser for a week.
• @DevJonny points out SRWare Iron, a browser created with the Chromium source code that apparently doesn’t have all the privacy concerns of Chrome.
• @BemusedWolf, who has come up with some colorful names for Firefox and Internet Explorer, might be interested in SRWare Iron.
• @SuperDuperCam had some colorful words to share about Firefox as well.
• @BrowserNews, the creator of the Dolphin3D browser, is touting it as “a better web browser.”
• @mrtech points us to a blog entry about what the Firefox team is doing about crashes and startup time.
• @usingpond wonders if Blackbird, which sells itself as an African American browser, is for real.
• @msacks makes reference to the Lobo browser, which is all-Java and uses a rendering engine called Cobra.
• @waynehastings and @deanq appear to be pleased with Chrome for Mac OS X, with the later giving a parting shot to both Firefox and Safari.
• @chrispy2004 appears to be displeased, however, claiming that Chrome for Mac OS X is the slowest browser he’s used in a long time.
• @GameFreak4321 doesn’t seem all that pleased either.
• @JasonTselentis thanks the “Facebook browser” for finally taking away Internet Explorer’s market share.
• @KileyG wonders what the threshold is for the number of open tabs before someone becomes unproductive.
• @muhanov discovers and shares the fact that the Android web browser doesn’t support FTP.
• @ganetsky wonders how it’s possible that no one has created a web browser named “Bowser.”  Good question!  Though to be fair, some people have referred to IE as the “Bowser” browser.
• @Andrew_James claims to be in “web browser heaven.”  I wonder if Netscape’s there.
• Both @jamienguyenle and @jinkhet refer to Chrome using sexual terms.
• @nicnab asserts that Firefox’s remembering of per-site zoom levels is enough to keep him hooked on said browser.
• @ConduitYourSite wonders what the best Twitter lists for browsers and web-related tools are.
• As I often have, @alex_crawshaw finds it ironic that you need to use a web browser in order to download an alternative one.
• @propstm wonders if IE6 users even realize what they’re missing out on, using such an out-of-date web browser.
• @derickthemacguy says Google Chrome looks like “a Fisher Price version of a web browser.”
• @souravghosh says that Mosaic “is considered the first browser to make the Internet easily accessible to non-techies.”
• @C_Hernandez_ heard that Camino is the fastest browser for Macs and apparently is going to check it out.
• @omegatron laments, as do many I’m sure, the fact that his mom doesn’t know the difference between a web browser and a web page.
• @Allyssen points us to a split-screen browser for the iPhone called iNetDual.
• @ericylai recommends the Bolt browser, which also happens to support a split-screen mode (check out the demo), for those tired of the default Blackberry browser.
• @IHtherapies finds KidZui, a web browser targeted at kids, very cool.

• @tr4st recommends Lunascape, the “world’s first and only triple engine browser,” to web developers.
• @sphereinabox wants to know what mobile web browsers, other than Safari, support offline storage.  If geek.com is to believed, it looks like Fennec does, too.
• And finally, @rodhilton loves that Ubuntu lets him use a web browser while the operating system is still installing.

That’s it for Twitter Watch #3.  Believe it or not, Twitter Watch #2 was so long ago that I was still using Summize to search for tweets.

Before I end this post, since we’re on the subject of Twitter, I should mention that Browsersphere is now on Twitter as well.  Just follow @Browsersphere for real-time updates, links to new site content, etc.

Months after launch, the browser had only captured a minuscule percentage of the market. The goal was to beat Microsoft with open source. Netscape couldn’t do it. And, according to [Asa] Dotzler, “we realized Mozilla couldn’t do it, either.”

While Mozilla 1.0 wasn’t a success, what followed certainly was. Two Mozilla contributors, Ben Goodger and Blake Ross, proposed taking things back to basics. The Mozilla source code was stripped down and rewritten once again, and all of the extraneous features were canned.

In late 2004, a faster, slimmer and easier-to-use browser emerged: Mozilla Firefox.

Hat-tip to @firefox and @mitchellbaker on Twitter.

• “Opera Turbo for fast browsing on slow connections” – this is essentially the same technology used by Opera Mini to compress content, saving bandwidth and time.
• “New visual tabs and sleek design” – the new design was previously covered here.
• “Speed Dial your way” – users now have the option of customizing the number of websites displayed or the background.
• “Web integration” – tell Opera to use your web-based email client or feed reader as the default for email and feeds, respectively, and it will.
• “Resizable search field”
• “40% faster engine and cutting-edge Web standards support”

While the bulk of those features are notable, it’s pretty obvious that the new visual changes will get the most immediate attention, followed by reviews of the underlying rendering engine, Presto 2.2, once people get some subjective and objective experience with it (does anyone still use a slow connection on their desktop anymore?).

For more on the web standards support added to Presto 2.2, check out Standards support in Opera Presto 2.2 and Opera 10 beta, which among other things, confirms that Opera 10 beta passes the Acid3 test.
