Mozilla won't make a 2009 deadline for releasing Firefox 3.6 and is giving itself more time to complete a major update, version 4.0.

The organization behind the open-source Web browser had predicted a final release of Firefox 3.6 in December 2009, but the Mozilla Web site now includes "ship Firefox 3.6" as a goal for the first quarter of 2010.

In addition, Firefox 4.0, which had been due in 2010, now is "aimed at late 2010 or early 2011," with a beta due in the summer of 2010, according to Mozilla.

Schedule delays are common in the software world, but browser development is furious these days with the arrival of Google's Chrome into the market, Apple helping to expand the frontiers of what the browser can do, Opera trying to dramatically speed up JavaScript execution and display performance, and Microsoft getting more ambitious again with Internet Explorer. "We've always been more quality-driven than time-driven, but we understand timing in the market matters to our users and our competitiveness," said Mike Shaver, Mozilla's vice president of engineering, in an October interview.

This past year felt like a rebuilding year for Firefox add-ons, with two new frameworks implemented to help guide the future of extensions. Personas gave Firefox on-the-fly theme-switching, and users can expect it to be part of the stable version of Firefox 3.6 when that gets released. Jetpack takes a similarly-minded approach to feature add-ons, allowing programmers to create feature-rich add-ons from little more than HTML, CSS, and JavaScript. Expect JetPack to eventually be part of Firefox by default.

In no particular order, here are eight other of our favorites:

Weave Sync gets added to your Options menu.

Weave Sync is another project from Mozilla Labs, although it's not as clear whether it will eventually end up in Firefox as a default feature. This homegrown tool for synchronizing Firefox across computers and devices introduces incremental syncing and a more-streamlined, less-obtrusive experience, fitting in smoothly in your Options pane. Although it still conflicts with some extensions, including the massively popular and arguably more essential AdBlock Plus, in general it works well and brings a long-missing feature to Firefox.

Multi Links is simple in purpose, but so effective that it's one of the best add-ons of the year. Right-click in a browser tab and drag it, highlighting multiple links in the box. By default, selected links open up in new browser tabs, although you can go into the options to choose whether you want them to open up in new windows, or be bookmarked instead. You're also able to change the color scheme of the box, and the outlines of the selected links, just in case you're into that sort of thing.

Originally known as SmarterFox, FastestFox is a multitasking fiend that helps make searching, pasting, surfing, and downloading faster. Highlight a word or phrase on the Web page and FastestFox will display a bubble filled with search engine icons. After a few seconds of inactivity, the search bubble fades away. The add-on automatically merges linked pages into one, which some users prefer for reading long articles, and it also allows you to check other search engines from any single engine's results page.

Users with WebReview installed can see a slew of links when they load up their browser, including their most visited pages, along with suggestions of what they should read based on past browsing history.

Whether you're looking for an unobtrusive panic button, or your just need to clear your screen of those 153 tabs for moment, HideTab can help you out. You can hide all of them at once, or merely one--just don't forget that the hidden tabs are still running in the background.

WebReview makes your start page smarter and more suggestive based on past browsing habits. It's a bit like the Speed Dial feature in Opera, Chrome's new tab page, or Top Sites in Safari, but Firefoxified. It tells you the last batch of tabs you had open, along with most visited pages. But it also shows you a group of sites you visit daily, along with a suggestion of sites you may be interested in going to. It sorts these out by what day it is, along with the time.

WebReview also offers a replacement history tracker, allowing you to search by domain or number of visits. Sites in the WebReview history come with thumbnail previews. Lastly, there's a Graph View, showing the breadcrumb trail of how you went from site to site for that entire session. You can also go back to specific days and see a large graph for the entire day. It's visually appealing and exploratory at the same time.

FastestFox can be a bit of overkill, and one of our favorite features from it is available separately. PageZipper takes stories split over multiple pages and "zips" them into one. It's a bit wonky, and doesn't play nicely with Flash- or JavaScript-based photos, but in general works well. It's also designed to be inoffensive to publishers, who often have legitimate reasons for splitting content into multiple pages. The "zipping" loads the next page in full below, including ads, so their potential revenue goes unharmed. The reader, on the other hand, benefits from significantly less stop-and-go clicking.

Wikipedia Diver hooks deep into your Wikipedia browsing to provide a fascinating look at what you've been researching. It organizes your Wiki searches down to the day, order, and session in which you visited the sites, making it easy to revisit old entries. Fortunately, all this data is kept on your local computer and not in the cloud, so there are no privacy issues. The reasonable offshoot of that is that it doesn't track external links you click on from within a Wikipedia article, but that's a small price to pay.

I use URL Tooltip in conjunction with several other, not-new-in-'09 add-ons to maximize my screen real estate when browsing. URL Tooltip is new this year, and is quite savvy for those with larger monitors. It reveals a link's full URL as a mouse-over tool tip, thus allowing you to hide your status bar at the bottom of Firefox if you've got nothing else in it. Along with Personal Menu and the Stop-or-Reload Button, and removing the search bar, I've been able to see more of what I want to be looking at on my screen when browsing.

Have a suggestion for the best new Firefox add-on of 2009? Or think I just got it all wrong? Tell me about it in the comments below.

The latest Opera browser preview version may not be entirely stable, but it's definitely got its jetpack strapped on. Opera 10.5 pre-alpha, for Windows and Mac, is the first browser that's not powered by Webkit to approach JavaScript rendering speeds previously reached only by Chrome and Safari.

Opera 10.5 pre-alpha introduces Windows 7 support and a slight redesign, along with a rocketing new JavaScript engine.

In empirical testing done on an HP desktop running an Intel Core 2 Q6600 at 2.66GHz with 4GB of RAM and Windows 7 32-bit, the pre-alpha scored 435.6 milliseconds in the SunSpider JavaScript benchmark. By contrast, Google Chrome 4.0.266.0, the most recent development build, notched 510.4 ms. The current stable build of Opera was more than 7.5 times slower, at 3284.4 ms.

Opera attributes this dramatic improvement to the new Carakan JavaScript engine, which they have designed from scratch to replace the Futhark engine in the stable build. Opera 10.5 also includes improvements to the Presto layout engine, and a new graphics library called Vega.

Other improvements noticeable in the pre-alpha include changing the URL address bar to include the same style of predictive smart search that Firefox and Chrome have, and the search and address bars now both remember searches, support deleting specific items, and have redesigned layouts.

The main browser interface has been redone, too. The tabs are now on top, the menu bar has been minimized behind a drop-down on the left nav, and the browser has better integration with Windows 7 and Snow Leopard. On Windows 7 there's Aero Peek and Jump List support to access Speed Dial and tabs from the Taskbar. For Macs, there's a unified toolbar, native buttons and scrollbars, multitouch gestures, and Growl support. Dialog boxes are now non-modal, which you means you can now switch tabs without a pop-up commanding your browser's focus, for example. This will affect verification and authentication pop-ups, and JavaScript alerts.

There are some known problems, including a lack of printer support in the Mac version and noticeably high memory usage. Users can expect these to get addressed before the stable build of Opera 10.50 is released. The Opera 10.50 official announcement and changes can be read here, while the current stable version of Opera 10.10 is for Windows, Mac, and Linux.

Mozilla, racing to release Firefox 3.6 by the end of the year, issued a fifth, and likely final, beta version of the new browser.

The open-source browser backer announced the new Firefox beta (download for Windows and Mac OS X) in a blog announcement Thursday.

Firefox 3.6 builds in a feature called Personas for customizing the browser's appearance, adds the File interface for better file management such as selecting what to upload, and, my personal favorite, placement of new tabs next to the ones that spawned them.

A total of 127 bugs were fixed since the fourth beta, but this time Mozilla didn't announce any new features. The first Firefox 3.6 beta arrived in October.

Mozilla had considered issuing its first Firefox 3.6 release candidate this week: "If we can go to build today or tomorrow, QA [quality assurance] will scrap Beta 5 and we'll release RC to the beta audience ASAP," the Mozilla meeting notes said.

If you want to see the scale of browser makers' ambition to remake not just the Web but computing itself, look no farther than a new 3D technology called WebGL.

The WebGL vision is simple. You're running around in a video game universe, blasting radioactive aliens--but you got there by visiting a Web site, not by installing the game on your PC.

This sort of computationally demanding chore contrasts sharply to with today's Web, whose top-notch programmers strain to reproduce bare-bones versions of the rich capabilities open to applications running natively on a computer.

WebGL, while only a nascent attempt to catch up, is real. WebGL now is a draft standard for bringing hardware-accelerated 3D graphics to the Web. It got its start with Firefox backer Mozilla and the Khronos Group, which oversees the OpenGL graphics interface, but now the programmers behind browsers from Apple, Google, and Opera Software are also involved.

Perhaps more significant than formal standards work, though, is WebGL support in three precursors of today's browsers--Minefield for Mozilla's Firefox, WebKit for Apple's Safari, and Chromium for Google's Chrome. Opera has started implementing WebGL, too, said Tim Johansson, Opera's lead graphics developer.

With a little tinkering--check the instructions and caveats below--you can give it a whirl, too. Overall, I was favorably impressed with the technology.

Its performance certainly isn't enough for a competitive first-person shooter, but it's approaching utility for casual gaming. And because of how WebGL elements can be integrated with the rest of a Web site's code, it's got some advantages.

What is WebGL?
WebGL is one of a handful of efforts under way to boost the processing power available to Web applications. It marries two existing technologies.

First is JavaScript, the programming language widely used to give Web pages intelligence and interactivity. Although JavaScript performance is improving relatively quickly these days in many browsers, programs written in the language are relatively pokey and limited compared with those that run natively on a computer.

Google Browser Size shows how much of a Web page browsers can show on average.

Google published a tool Wednesday called Browser Size that lets Web developers gauge how much of their pages are visible in people's browsers.

With its own analysis, the search giant found that a lot of people couldn't see the download button for Google Earth because they had to scroll before it would show in their browser. Revamping the page increased download rates 10 percent, according to a blog post by Browser Size team member Arthur Blume.

The tool loads a Web page behind a pastel overlay that indicates what fraction of people can see a particular point on the Web page. The upper left is of course 100 percent, but when the point is farther down or toward the right, fewer and fewer can see it. The overlay statistics are based on a fraction of the people who visit the Google.com home page, said programmer Bruno Bowden.

"For example, if an important button is in the 80 percent region it means that 20 percent of users have to scroll in order to see it," Bowden said.

I'm intrigued by this sort of data. It's interesting to see the jump between old-style screens with a 4:3 aspect ratio and newer HD-style models that usually are in a wider 16:10 proportion. I'd be particularly curious to see how the overlay changes from one Web page to another--for example, I'd imagine gaming site visitors have bigger screens than mainstream Web pages.

Here's a hint if you're reading this on a laptop with a modest screen size: to see more of the Brower Size overlay, try pressing Ctrl-minus to zoom out.

I spend a lot of time looking at Web pages and have no particular fondness for scrolling. I therefore appreciate various efforts to maximize browser real estate devoted to actual Web content. Perhaps Google's tool will help on the Web design end, too, helping justify redesigns to put the good stuff in plain sight.

Mozilla has updated its Firefox browser to patch three critical security holes.

Firefox 3.5.6 and 3.0.16 both fix earlier memory corruption issues. "We presume that with enough effort at least some of these could be exploited to run arbitrary code," the security advisory said.

In addition, the earlier version of Firefox 3.5 had two critical vulnerabilities in its technology for playing Ogg-format media, one with the liboggplay media library and one with the libtheora video library.

The patches are among 62 fixes in the new Firefox, software that's translated into dozens of languages and runs on multiple operating systems. Users of the OS/2 operating system will be delighted to know that problems with Firefox's full-screen mode and with print preview have been resolved.

"We strongly recommend that all Firefox users upgrade to this latest release," Mozilla said in a blog posting. By default, Firefox downloads updates automatically then prompts users to restart when it's ready; updates also can be retrieved through the "check for updates" menu option.

Mozilla plans to cease supporting Firefox 3.0 in January. Meanwhile, a significant update, Firefox 3.6, is due by the end of the year.

Correction 1:23 p.m. PST December 17: This story was corrected to note that it was the earlier versions of Firefox that suffered the vulnerabilities.

Even without extensions, Google Chrome's market share grew phenomenally during its first year. Now that the No. 1 most-requested feature comes baked into the Windows (beta and development) and Linux (beta and development) versions, it's time to look at some of the best extensions available for the upstart browser.

The No. 1 extension on my list is the No. 2 most-requested feature for Chrome: RSS support. The RSS Subscription Extension allows Chrome to automatically detect RSS and Atom feeds on a page. It's not entirely clear why this isn't a default feature since it's part of every other browser, but at least now there's a way to add it.

There are a host of Google-service related extensions, all based on letting you know at a glance if there's an update for you to check in on. The Google Alerter covers Gmail, Wave, and Google Reader, although there's also individual support for them as the Gmail Checker, Google Wave Checker, and Google Reader Checker. There's a Google Calendar Checker, too.

The Google Translate extension adds a slick pop-up toolbar.

The Google Tasks extension hides your tasks behind a button that opens a list of them when clicked. The most useful Google-related extension is for Google Translate, which will offer on-the-fly translation of a site that doesn't appear in your default system language.

Expect security to be as big a subcategory of extensions for Chrome as it is for Firefox. Popular and effective secure personal password storehouse LastPass provides a safe and near-universal way to manage your passwords, making them easily accessible without compromising their integrity. LastPass also supports Firefox and Internet Explorer on Windows, making it an excellent one-stop solution. When Chrome's extensions get activated on the Mac version, the reasons for using LastPass will become even more compelling.

Also cross-browser, Web of Trust evaluates Web sites based on consensus. It may sound counter-intuitive to some, but it's proven in the past year to be an especially effective tool for determining whether you can trust that sketchy link you're thinking of clicking on.

UnShorten.com is one way to see what that shortened URL is hiding, but ChromeMUSE is another. This useful extension not only can shorten URLs via several different shortening services, it can also expand embedded short URLs automatically.

FlashBlock is a good way to kill Flash and Silverlight-based content. It leaves a blank spot where the ad or embedded video would've been, which you can then selectively load by clicking on it.

Despite the name, AdBlock+ should be avoided. It's not made by the same publishers who manage AdBlock Plus, the popular and effective ad-blocker for Firefox. This is actually a fairly serious problem with Chrome's extensions, where unknown entities are appropriating identical or similar names to well-known and trusted Firefox add-ons for what amount to nefarious purposes. So far, the ad-blocking extension that most users seem to be trusting in Chrome is AdBlock, but don't be surprised if it causes more problems than it solves until there's more consensus on these name-squatters.

AniWeather offers an animated weather pop-up.

On that note, there are some excellent Firefox add-ons that have been ported successfully to Chrome. Bookmark synchronizer Xmarks has a beta version for Chrome, as does IE Tab for viewing rendering sites with Internet Explorer's engine within Chrome, and the resource-heavy but still-fun way to view visual media Cooliris.

Facebook for Chrome simplifies Facebook access, putting news feed and status updating in your toolbar. YouTube Downloader grabs Flash video embeds and saves them to your hard drive but interestingly doesn't come from Google itself. AniWeather is another, providing those without windows an excellent way to see what meteorological events are going on outdoors. iMacros will run Greasemonkey scripts and allows users to create their own solutions for repetitive data entry and tasks. The one I can't live without is another name-squatter, AutoCopy. It will copy any text to your clipboard when you highlight it. Unlike the Firefox version, it doesn't open any options when you finish highlighting, so it's a bit hard to tell if it's working as it should.

TooManyTabs cleverly secrets away tabs you want to keep handy but out of your active memory.

(Credit: Screenshot by Seth Rosenblatt/CNET)

TooManyTabs isn't TabMixPlus for Chrome, but it does something that TabMixPlus can't because Firefox doesn't yet support it. TooManyTabs manipulates Chrome's tab process isolation in a useful way, so you can move tabs to a holding dock where they're no longer eating memory, but they're still easily accessible. Click on the toolbar button and it opens up a window that displays your active tabs. Arrows next to each one let you move it to the nonfunctional area. A helpful indicator on the toolbar button tells you how many active tabs you've got. Conspicuously missing is drag-and-drop, so hopefully that's coming.

Aviary Screen Capture is another extension that offers Chrome-only features. It lets you take a screenshot of any Web site you're looking at and then automatically opens it in Aviary's image-editing Web suite to streamline your work flow.

The lack of a status bar in Chrome means that the management icons for extensions, if they have them, get added to the navigation bar, something that may annoy users who prefer Firefox's greater level of extension-placement customization. However, it's definitely a more visible placement, and may encourage users to keep their installed extensions to a utilitarian minimum.

More extensions can be downloaded from Google's site or Download.com.

Currently, extension support hasn't been activated in the Chrome for Mac, but that's expected no later than January 2010. There's also some notable popular Firefox extensions that aren't in Chrome yet, such as FoxyTunes. If I've skipped a favorite Chrome extension of yours, or if there's one for Firefox that you're dying to get in Chrome, tell me about it in the comments below.

Google's browser has passed Safari in terms of worldwide browser usage--at least by one measurement.

NetApplications' measurements of browser usage share, which track which browsers individuals use based on visits to the company's network of Web sites, gave Chrome the third-place spot after No. 1 Internet Explorer and No. 2 Firefox for the week of December 6 through 12, according to a Computerworld story Tuesday. Chrome had 4.4 percent share to Safari's 4.37 percent.

Google released beta versions of Chrome for Mac OS X and Linux on December 8. Earlier, only developer channel versions had been available. Google plans to release the "stable" versions January 12, according to the Chromium development calendar.

Take these usage share numbers with a grain of salt. Even though 0.03 percentage points still is a lot of people in the real world, it is a small fraction, and a change in Net Applications' assumptions in August led to share changes two orders of magnitude more dramatic. Weekly statistics also vary: Although Firefox cleared 25 percent share in one week of November, it averaged only 24.72 percent for the overall month.

I've asked various browser makers about how trustworthy they view NetApplications' statistics to be. The answers generally are favorable but not ringing endorsements.

Regardless of the precise details, though, the Chrome trajectory is upward: its November usage share was 3.93 percent to Safari's 4.36 percent.

And although Google relied on word of mouth for promoting its original online search product, it's taking a more active role with Chrome. The latest example: a "Chrome for Christmas" site that lets people send invitations to download Chrome.

Firefox proved that a browser not bundled with an operating system can be successful, and Chrome could show the idea isn't a fluke if its growth continues.

Google is promoting its browser through this 'Chrome for Christmas' e-mail campaign.
