Webware

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.

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.

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.

eBay may have recently sold off Skype to the highest bidder, but the VoIP app for desktop and mobile is still in development.

On Thursday, Skype announced Skype 4.2 for Windows beta and a new beta build for Symbian phones. Skype 4.2 beta for Windows desktop users is small as updates go, reinstating Skype Access--a Wi-Fi hot-spot connector--and call transferring that Skype had removed when overhauling its app and updating to version 4 (now in version 4.1), a build that includes screen-sharing.

You can scrutinize the full release notes here.

In addition to tightening up Skype for the desktop, the company announced it will issue a limited beta release for Symbian Series 60 handsets. There's compatibility for 17 Nokia handsets at launch, with use on more phones on the way.

The feature set is basic at present, with just the following features in place:

• Free Skype-to-Skype calling
• Call phones with Skype credits or subscription
• Receive calls on your online number
• Instant messaging
• Group conversations
• File sending and receiving

It's not fully baked yet, but Google Chrome for Mac reaches a major milestone with the release of an official beta version. More stable than the development version, this Chrome beta brings rocket-powered browsing to Apple's computers--but it still lacks some key features.

And just how does it compare with Safari? Watch and find out, and also check out our hands-on review of Google's next move forward for Macs.

Google released the first beta build of its Chrome browser for Mac and Linux earlier today, and it's hard not to be impressed when putting the Mac version through its paces. Chrome for Mac still lacks some of the key features that are currently available in the Windows beta, but this is a browser that most people should feel comfortable using.

As expected, Chrome on the Mac is still far superior to Firefox and even its WebKit cousin Safari when it comes to JavaScript rendering. Using the SunSpider JavaScript benchmark, Chrome came in 1.8 times faster than Firefox by scoring 738.8 milliseconds. Safari notched 1,155.8 ms, while Firefox 3.6 beta 4 completed it in 1,330 ms. This is semicasual testing, but it does provide a ballpark from which we can see the gross differences between the browser's JavaScript rendering capability.

Chrome for Mac also starts up fast, by which I mean the point from clicking the browser icon on the dock to when Google's search page has finished loading. On Chrome it took less than 2 seconds, while Firefox took slightly more than 2 seconds, and Safari was just less than 3 seconds.

Google Chrome beta on the Mac won't look new if you've been using the dev build.

Although Chrome's first non-beta for Macs is expected within the month, currently the beta doesn't have all the features of its Windows-based sibling. Most notably missing is extension support, which had been in the developer's build but was recently disabled. The timing of this is somewhat unfortunate, considering that Google just officially launched the Chrome extensions gallery. It also lacks bookmark syncing, the bookmark manager, and the cookie manager.

When firing up a site, Chrome will occasionally show nothing but white space until the page is finished loading. In several hours of hands-on use, this was the only experiential flaw encountered--although the beta could easily be hiding more.

Even with these drawbacks, Google Chrome beta makes for an excellent quick-use browser on the Mac, and can be more or less used with confidence on a regular basis, if not as a go-to browser.

The beta version of Chrome for Mac OS X is available. Google released its browser beta for Linux too.

Two key pieces of Google's effort to make Chrome a more competitive browser fell into place on Tuesday as Google released beta versions of the browser for Mac OS X and Linux.

Tuesday's software release is a version of Chrome that had previously been available only as developer preview software for Mac and Linux machines. "It took longer than we expected, but we hope the wait was worth it," product manager Brian Rakowski said in a blog post.

Macs are widely used, if not as common as Windows machines, and there's been some demand in tech circles for the Mac version of Chrome. Linux, while less widely used among ordinary computer users, has importance of its own: it's the foundation for Chrome OS. That's the browser-based operating system Google hopes will be popular on Netbooks starting next year.

According to the Chromium development calendar, the beta versions are scheduled to graduate to the next level of maturity, "stable," on January 12. Chrome for Windows graduated out of beta almost exactly a year ago.

Google doesn't emphasize product version numbers in the project, instead automatically delivering updates behind the scenes to the browser that take effect when it's restarted. But it does use version milestones to keep track of development internally.

The biggest new feature of Chrome 4.0 is support for extensions, which let people customize the browser. In the Mozilla world, they're called add-ons, and they've been a big part of Firefox's success.

Extensions aren't useful, though, unless people can find them. Google on Tuesday also launched a Chrome extensions gallery page.

There are more than 300 extensions available for Chrome, extensions programmers Aaron Boodman and Erik Kay said in a blog post.

However, extensions on the Mac aren't yet available, though they had been for a time in the developer-preview version. "Extensions aren't quite beta-quality on Mac yet, but you will be able to preview them on a developer channel soon," Rakowski said.

Also on the Chrome for Mac to-do list: a bookmark manager, PDF viewing in the browser, bookmark synchronization, 64-bit support, and my personal favorite differentiator of Firefox 3.6 on the Mac, full-screen support.

Why try Chrome?
For those of you new to Chrome, here's a brief version of why it's my default browser on both Windows and, as of about a month ago, Mac OS X. Your preferences and needs may vary, of course, and I still use Firefox every day, too.

• Speed. It's fast to start up, though not quite as snappy as it once was now that it's not so bare-bones, and rivals are making progress. It's also fast loading Web pages and running JavaScript programs on them.

• Tabs. I spawn innumerable new tabs all day long, and when it takes a long time (I'm looking at you, Internet Explorer), I get infuriated. I also like the order in which new tabs arrive, a style Firefox is mimicking.

• The omnibox. It's a single bar that merges the utility of an address bar and search bar. I hit Ctrl-L (on Windows) or Command-L (on Mac) to pop my cursor up there, and start typing. One nice--if somewhat obscure--feature is fast site search on some domains, so for example I can type A, M, tab, and up pops an Amazon.com icon; what I type afterward is entered as a search on Amazon. That conveniently gets me straight to the search results so I don't have to see yet another Kindle ad.

• A minimal user interface. When browsing, I like my user interface to step aside and make way for the Web page. Scrolling was a wonderful innovation in computers a few decades ago, but I like to avoid it when I can. Chrome puts tabs in the real estate ordinarily devoted to a program's title bar and shuffles the menu controls off to the right of that tab strip (though the Mac version gets a regular menu bar).

Another potential perk: avant-garde Web technology, including WebGL and O3D for accelerated 3D graphics and Native Client for speeding up Web apps with direct access to a processor, are being built into Chrome. Another such Google project, Gears, is already built into Chrome--though Gears doesn't work on Mac OS X 10.6.

There are things you might miss--the full panoply of Firefox extensions, toolbars from Google or others, print preview. And the "browser not supported" error messages on various Web pages are annoying, though in my experience there's rarely an actual compatibility problem. Overall, I like it.

Is Google spying on me?
If you're worried about what new data Google will be able to harvest on you, I recommend a close read of Google's Chrome privacy page. This doesn't worry me much, but I may be insufficiently paranoid. In my opinion, the biggest thing is that Google stores 2 percent of the data it gathers when people type text into Chrome's combination search and address bar, called the omnibox.

That means Google can see not only what you're searching for (as it would for any Google search), but what Web site addresses you're typing as well. The data is anonymized within 24 hours, Google said.

Also, Chrome has a feature called DNS pre-fetching that tracks down the Internet server addresses on Web pages in anticipation that you'll be clicking links on the page. So Chrome--and Google, too, if you're using Google Public DNS--retrieves this information from the Internet.

Mozilla, determined to release Firefox 3.6 before year's end, is also determined to squeeze as many features as possible into the new browser.

The latest example: support for the File interface that adds more sophistication to uploading and some other chores.

Support for the feature is one of the 133 changes that arrived in Firefox 3.6 beta 4, which the Mozilla project released Thursday for Windows, Mac, and Linux.

The File API (application programming interface), a draft standard at the World Wide Web consortium, lets browsers handle files better. Among its abilities are uploading multiple files at once, showing thumbnail previews of images that have been selected for upload, breaking a long video upload up into chunks to protect against network interruption problems, and integrating with drag-and-drop Web applications.

While many software projects use beta testing periods to shake down their code, Mozilla isn't afraid to add new features as it goes. That can mean new ideas arrive sooner, of course, but it also can delay the completion date of the new version. What was to have been a quick Firefox 3.1 release was pushed back months as new features were added and the version ultimately was renamed Firefox 3.5.

For those who want to dig into the File interface, Mozilla offers a Web developer guide to using it.

The beta-testing periods aren't just important for debugging Firefox itself. New versions often don't work with older add-ons that people install to customize the browser, so beta testing gives some time for programmers to update those add-ons. Mike Belzner, Mozilla's director of Firefox, said 70 percent of add-ons are now compatible with Firefox 3.6.

The developer preview version of Chrome now promotes an as-yet unworking link to an extensions gallery.

Google is on the verge of launching a Web site to showcase its extensions to customize what its browser can do.

The company's latest developer preview edition, Chrome 4.0.249.0, promotes the feature on its opening screen and its new-tab page. "New! Google Chrome now has extensions and bookmark sync," the page reads, offering a link to a site that's not public yet, https://chrome.google.com/extensions. (Bookmark sync is already available.)

Extensions and support for Mac OS X and Linux are the headline features of Chrome 4.0. It's available as a beta for Windows, with Mac OS X and Linux beta availability expected in early December. According to the Chromium development calendar, the beta is planned for December 8 release and the stable release of Chrome 4.0 is due January 12.

A number of third-party galleries for Chrome extensions already are available, but programmers for the project have said on mailing lists that a Google site is planned. Earlier this year, Google shipped a version of Chrome that pointed to a collection of visual themes before the Chrome themes gallery was actually live to the public.

Extensions are a key asset of one Chrome competitor, Mozilla's Firefox; extensions permit people to customize the browser and add new features without burdening the overall project. Firefox is getting a new extensions framework, Jetpack, starting with version 3.7 due in the first half of 2010, and Mozilla has just launched its own Jetpack gallery.

Visual thumbnails for tabs are all new in Opera Mobie 10 beta.

Opera impressed us a few months ago with its beta release of a restyled Mini browser for Java phones. Early in November, they did it again with a standalone mobile browser for Symbian Series 60 handsets that adheres to Opera Mini 5 beta's glossy master design. And on Wednesday, Opera repeats what it hopes to be mobile magic with Opera Mobile 10 beta for Windows phones.

The free Opera Mobile 10 beta starts off with a customizable Speed Dial screen, composed of nine preview thumbnails that whisk you off to a favorite site. Browser tabs receive a new treatment that echoes those thumbnail previews, and other features like the Password Manager get a few behind-the-scenes adjustments.

As with the recent betas for Java and Symbian phones, Opera Mobile 10 beta lacks some features for Windows phones that Opera expects to restore by the time it approves the app for general consumption. Opera Link, its bookmark- and favorite-syncing service, is among the laggers.

Our First Look video of Opera Mobile 10 beta (below) sees the browser tested on a Symbian phone, but it will look and work almost identically on Windows phones. Press "play" to get a good idea of what's in store, including those known bugs.

Note: Since our video, Opera has released an update for Symbian phones that can now handle font for several Asian languages.

Windows Mobile owners can download the mobile browser beta free by navigating to m.opera.com/mobile/ from the phone or www.opera.com/mobile from the desktop. Opera Mobile 10 beta will replace the Opera Mobile 9.7 beta that has previously been available for Windows Mobile phones.

Windows users: how do you like Opera's reworking of the browser? Let us know in the comments.

Google plans to release a Mac beta of Chrome in early December, judging by some chatter on a mailing list for the browser.

Chrome 4.0 is available today as a beta version for Windows but only as a rougher developer-preview version on Linux and Mac OS X. The standout feature of the new version is customization through extensions, a technology that long has been a core asset of another open-source browser, Firefox.

Google has been moving to a new extensions presentation technology called Browser Actions that let people interact with extensions through a small button toward the upper right of the browser window. "We've noticed that many of you have updated your extensions to take advantage of the new UI. We'd like to encourage the rest of you to do so as well," said Nick Baum, a Google Chrome product manager, in a mailing list posting.

But here's the hitch: Browser Actions only work on Windows and Linux right now. That means those building extensions will leave Mac Chrome users behind for a time. But in telling those developers they won't have long to wait, Baum mentioned the deadline for the beta version.

"The earlier you switch, the more time you will have to polish your experience for our Beta launch in early December," he said.

And Google is on the case for adding Browser Actions to the Mac version of Chrome.

"We realize this means dropping Mac support for a couple of weeks, but we already have people working on that," Baum said. "If you prioritize the Windows and Linux versions, we'll bring you cross-platform parity as soon as we can!"
