It appears that the Google Goggles search-by-sight tool could soon work not just with mobile phones, but through Google's Chrome browser, too.

"I am working on a 20 percent project to facilitate the input of Web image searching," Google programmer Xiuduan Fang said in a post Tuesday to the Chrome Extensions mailing list titled "Chrome extension for Web Goggles. The 20 percent figure refers to a Google program that permits engineers to devote a fifth of their time to projects of their own choosing.

"We would like to have some browser extensions so that the user can drag a Web image and drop it in an input box on the toolbar...The search results of the image will be shown," Fang said, then asking for advice on how to write it up for Chrome. The original message isn't online, though a response with some pointers is.

Google Goggles currently is available as an application for phones running Google's Android operating system, but Google is working to release other versions, too. A Web browser interface would expand the service's availability beyond phones. Though there are plenty of situations where you might want to point your phone at a subject while out and about, there also are plenty of images on the Web that might provoke further inquiry.

The Goggles feature works by comparing an uploaded image to a database of billions Google has collected and analyzed. It can recognize landmarks and read the text of wine labels, among other things, but until Google works out privacy controls it doesn't make use of its ability to recognize faces. The effort is part of Google's unending effort to expand the scope and utility of its search service.

The new beta version of Google's Chrome browser adds support for extensions, though at present with some limits on user interface choices for programmers.

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.

The present interface for developers to upload their Chrome extensions.

Google has opened up its gallery for developers to share Chrome extensions, a step that soon should make it easier for people to customize the open-source browser.

Aaron Boodman, a leader of the Chrome extensions effort, announced the move on a mailing list posting Monday, and programmer and "gallery master" Lei Zheng shared details in a blog post.

So far, only uploads are permitted. Google plans to let some testers use the gallery to download extensions, too "in the next few days," Zheng said. "We are making the upload flow available early to make sure that developers have the time to publish their extensions ahead of our full launch."

Extensions, a major asset of the Firefox browser and the headline feature of the upcoming Chrome 4 beta, let people modify the browser more to their liking. With them, the browser itself doesn't have to be bogged down with numerous features and configuration options that most people don't want.

One feature of Google's system is that add-ons are automatically updated on Chrome users' computers once the developer uploads a new version.

For developers, the extensions gallery comes with a set of terms and conditions.

One nugget in the legalese: expect Google to use a rating system, as it does for other sites including Android applications and YouTube videos. It's all part of Google's philosophy of using user data to help automatically manage its Web properties in a way that, the company hopes, will be helpful to those who use its sites.

According to the terms and conditions: "The gallery will allow users to rate products. Along with other factors, product ratings may be used to determine the placement of products on the gallery with higher rated products generally given better placement, subject to Google's right to change placement at Google's sole discretion. For new developers without product history, Google may use or publish performance measurements such as uninstall rates to identify or remove products that are not meeting acceptable standards, as determined by Google."

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.

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!"

MOUNTAIN VIEW, Calif.--Thunderbird 3, an update to the e-mail software that Mozilla hopes will give it some of the advantages its Firefox browser has enjoyed, is due to arrive in near-final form next week.

Mozilla Messaging plans to issue release candidate 1 of Thunderbird 3 as soon as Monday, with the final version expected later in November, the e-mail-focused subsidiary of the Mozilla Foundation said Thursday.

"We're down to the last few bugs," said Chief Executive David Ascher. "Feedback with the last beta was enthusiastic." Thunderbird 3 beta 4 can be downloaded for Windows, Mac, and Linux.

Thunderbird doesn't get as much attention as Firefox, the chief product of the Mozilla Foundation's other subsidiary. But with Thunderbird 3, Ascher and Mozilla Messaging are trying harder to take advantage of one technology that's helped the browser's fortunes: add-ons. They could be written for Thunderbird 2, but only with what Ascher termed an act of heroism; Thunderbird 3 makes add-ons much easier.

One area where add-ons show up is a new Thunderbird 3 feature, Google and Yahoo calendar functions in the software--using its built-in Firefox engine for handling Web pages, naturally.

"There are a bunch of actions that start in e-mail that really involve the Web," Ascher said. Another example he said Mozilla Messaging will write if some enterprising person doesn't do it first: an add-on to help people assess whether to follow a particular Twitter user who just signed up to follow you.

Another add-on that's already under way is Lightning, which parallels Outlook's calendar functions. A Thunderbird 3-compatible version should arrive about the same time, he said. Ultimately, Thunderbird should be able to integrate with either Lightning or Web-based calendars, including the automation of operations such as accepting event invitations.

Better search
The add-ons also dovetail with a significant new Thunderbird feature, improved search. With Thunderbird 2's folder-based search approach, people often didn't set up searches so they could find what they needed. With Thunderbird 3, it returns all results that match the text, not just what's in a particular folder.

"It's really important to search everywhere," Ascher said. As with Google, "You type a word, and you get results."

Of course that can retrieve a lot of unwanted results. So the search results page offers a variety of ways to winnow that search down--limiting it to particular people, to messages with a specific tag, or to a particular time frame selected from a timeline that presents messages using the search term.

These functions to refine the search, which Mozilla Messaging calls "facets," are another area where add-ons can help, Ascher said.

Also coming in Thunderbird 3 is a simpler start-up process. The software is set up in advance to automatically set up the increasingly complicated server configuration for various accounts. I tried it with Gmail, and it indeed was up and running in moments after I entered only my name, e-mail address, and password. The software comes with several profiles built in, and it makes intelligent guesses if it doesn't know, but people will be able to write their own modules that can be shared, too.

Another feature in the new version is the archive, a feature borrowed from Google's Gmail that's a kind of digital purgatory. E-mails sent to the archive are still available through search, but they don't clutter up the inbox. Folders are still available for those who want to file messages the traditional way.

"The original idea of e-mail, putting messages in folders one by one, was reasonable when we got ten messages a day. Now that we get a couple hundred or more, that's a huge burden," Ascher said. "We made archive really easy and complemented it with (an) easy-to-use search experience.

Streamlined interface
One big interface change is the addition of tabs. Mail accounts, folders, and individual messages can show as new tabs rather than new windows. It's one of a number of efforts to provide a more streamlined interface.

One other is moving some message-specific operations to the message window--reply, reply to a mailing list, forward, archive, and other options. Another: the main toolbar has been cleaned up so only essential actions show, though others can be added through customization. And people can be added to the address book with a single click of a star next to their names--not unlike Firefox 3.5's one-click bookmark operation.

Some routine tasks--labeling a message as junk, for example--are designed to be faster, he added.

"If you look at the number of seconds saved over the population of Thunderbird users, it tends to be several lifetimes per year," Ascher said.

One new feature in Thunderbird 3 is a simplified account setup. You enter three bits of information, and Thunderbird often can take it from there.

More people will get a chance to try out bookmark synchronization with Monday's release of a beta version of Google Chrome for Windows.

Google introduced the bookmark sync feature for the developer-preview version in August, but now it's also in the better-tested beta version, Chrome 4.0.223.16. However, there's still no Chrome beta for Mac OS X or Linux.

In a video explanation, Google's Anthony LaForge somewhat breathlessly describes how the sync feature can keep bookmarks the same on multiple machines. That's a fair point, but let's be realistic here--bookmark sync in Chrome is more catch-up than paradigm shift. Indeed, with the popular Xmarks extension--in the works for Chrome, people can synchronize bookmarks among multiple browsers, not merely multiple computers.

And Chrome's clever message-based sync technology notwithstanding, Chrome bookmarks would be a lot more magical if they synchronized with the Google bookmarks service, which is linked with iGoogle and the Google Toolbar.

Speaking of extensions, one of the 4.x series' biggest features is the ability to accommodate extensions, but because Google is shifting the extensions interface, the feature isn't enabled in the beta version. Chrome is released in three versions: the roughest, fastest moving developer preview, the more stable beta, and the stable edition for the broadest audience.

The 4.x series has other significant features, too, though it's not clear whether they'll arrive in the beta or stable versions. One is Google's Native Client, which lets JavaScript applications take more direct advantage of a PC processor's horsepower through a careful security mechanism. Another is WebGL, a 3D interface that does the same with hardware-accelerated graphics.

Together, the features have the potential to dramatically improve the power and sophistication of Web-based applications. That's particularly interesting given that Google is building Chrome OS, a browser-based operating system.

The Mac version isn't in beta yet, but it's a priority.

"Our goal for this Friday is to be able to count our Mac P1 M4 release blocker bugs on one hand (we're in the 20s now)," said Chrome programmer Mike Pinkerton in a mailing list announcement on Monday. P1 bugs are priority-one; M4 refers to milestone 4, or version 4.0.

And Google is willing to put more manpower onto the Mac version, he added. "Everyone should have their P1 list practically at zero by the end of this week. If you are not going to be able to reach this, let me (or other triage folk) know ASAP so that we can get you some help.

Chrome edged up to 3.6 percent of browser usage for October, its highest showing so far in Net Applications' statistics since the browser's first public release 14 months ago. That's within striking distance of third-place Safari at 4.2 percent, but still well short of second-place Firefox at 24.1 percent and dominant Internet Explorer at 64.6 percent.

Chrome has helped fan the browser war flames even without becoming dominant, though. In particular, it's helped increase the emphasis on performance such as the speed to load the software, load Web pages, and run Web-based JavaScript applications. Here, more than with bookmark sync, Google's chest-thumping has some merit:

"As with every release, this new beta comes with many speed improvements. In particular, as Web applications we use every day become increasingly dynamic, browsers like Google Chrome need to be able to construct and change elements on web pages as fast as possible," said programmers Idan Avraham and Anton Muhin in a blog post. "We've improved performance scores on Google Chrome by 30 percent since our current stable release, as measured by Mozilla's Dromeao DOM Core Tests, and by 400 percent since our first stable release."

There has been some slowdown with the arrival of Chrome extensions, though, so Google will have some more optimization work to do to keep the browser in fighting trim.

Updated 9:57 p.m. PST with further details on the Mac OS X beta priority.

Support for extensions to customize Chrome, the top-requested feature for Google's browser, has begun arriving for adventurous users.

Previously, extensions worked only for those who enabled the feature with a command line switch. Now the feature is enabled by default in the developer preview version of Chrome on Windows, Aaron Boodman, the Google engineer who oversees the extensions work, said in a blog post Wednesday.

"We're ready for a few more people to start using extensions--the kind of adventurous people who populate the dev channel," said Boodman, who earlier in his career developed the Greasemonkey tool that permitted extensive customization of Firefox.

Work is already under way for some popular extensions, including Yahoo's Delicious for social bookmarking and Xmarks for bookmark synchronization.

Extensions are enabled by default only for Chrome's Windows users right now. "We've also enlisted some help to get extensions up to speed on Mac and Linux," Boodman said.

The extension-programming interfaces have been changing, and more changes are coming to the user interface. Those who want to start developing extensions should look at the new Chrome extension documentation.

Chrome extensions are written with the same programming technologies as are used for Web pages themselves--HTML, CSS, and the like. Mozilla has a related extension effort called Jetpack under way for Firefox.

Some selected Chrome users who want to synchronize browser bookmarks with their other browsers now can get a start.

Xmarks, whose browser addition can keep bookmarks synced across Firefox, Internet Explorer, and the Mac OS X version of Safari, has released an alpha version of a Chrome extension to selected testers.

"We've been swamped with requests to create a version of Xmarks for the Google Chrome browser. We're hard at work on that and, thanks to some new APIs (application programming interfaces) from Google, are pleased to report that we have Xmarks synchronization working in the Windows developer channel for Chrome," Xmarks' Colin Bleckner said on the Xmarks blog Sunday. Xmarks formerly was called Foxmarks.

"We're doing this (closed test) so we can catch any serious issues we may have missed before letting thousands of users try it out. Hopefully we'll be able to ramp up our user count quickly," Bleckner said in a mailing list message.

The move comes just after Google released its own bookmark synchronization feature in the Windows version of Chrome, but it doesn't synchronize bookmarks with other browsers or even with the Google Bookmarks service.

Google is working hard on its extensions support in Chrome, but the feature remains a work in progress. Indeed, Aaron Boodman, a Chrome extensions developer, marveled that Xmarks produced even an alpha given the pace of change. "I'm shocked you could get anything at all done with us breaking everything every other release," he said in a mailing list message about Xmarks' announcement.

Another early extension for Chrome, one for Yahoo's Delicious bookmarks service, also is available.
