Though the Opera browser isn't open source, it's free and its new server-in-a-browser feature, Unite, is really making significant inroads toward online collaboration. If Chrome and Firefox are to keep their edge over Opera, their development teams had better sit up and take notice.

Opera's Unite technology lets users run chat rooms, host Web sites, and share files that even people not using Opera can access. The interaction is all done via a central Opera Unite server ? Opera Unite uses a proxy between the server and its clients (found at operaunite.com) to avoid the need for any special firewall configuration, writes the development team. Unite launched today with six features but is calling on the Opera community to design and create any new services they'd like to see available.

Read on to have a look at what Opera unite can already do and why Google and Mozilla haven't cornered the market on browsers just yet.

After months of waiting, Linux (and Mac) users woke to the happy news this morning that Google is inching ever closer to a usable version of its Chrome Web browser for Linux. Usable is the keyword here because the new developer version Google released last night is anything but. At least it gives us a peek, though, at what to expect when the much-anticipated browser is finally ready for prime time.?

According to Mike Arrington at TechCrunch, several sources say that the Mozilla-based social browser, Flock, will soon shed its Mozilla code base and start using Google's Chrome framework for future releases.

Flock's CEO, Shawn Hardin, responded to Arrington's post, saying that the browser's upcoming 2.1 release is being developed, and will be released with, its traditional Mozilla underpinnings. Hardin does not explicitly say that Flock will move to Chrome, only that the browser space has been heating up rapidly in the last few months, and that the Flock development team will continue to make architectural decisions that balance what's best for our users and what's best for Flock as a business.

Via OSNews comes word that the developers bringing Chrome to Linux have opted to use GTK over Qt as the browser's framework.

The development team's decision wasn't an easy one. The questions they addressed about Chrome's appearance and behavior, what end-users need and expect, and how to make it work smoothly on the Linux desktop are highly subjective, and in some cases, emotionally charged. The FAQ on the Chromium developer's site states that while both toolkits are capable of doing the job (WebKit handles most rendering with the exception of some form controls and dialogs), the team opted for GTK due to their level of familiarity with it.

TechCrunch's Michael Arrington is reporting that Google's vice president Marissa Mayer told him in an interview that Chrome will be coming out of beta.

Mayer didn't give a definite time frame, but one would assume that this would mean sooner rather than later. This announcement is a little surprising for a few reasons.

On Monday, the Mozilla team announced the general availability of Firefox 3.1 beta 2 for testing. Aside from increased localization support, a new Private Browsing mode, new tab switching and preview behaviors, and support for a number of new web technologies (such as the W3C Geolocation API and offline applications), the new beta release uses the TraceMonkey JavaScript engine by default, and has made tweaks to the Gecko engine to speed content rendering.

The Mozilla Foundation's Mitchell Baker reported yesterday that Mozilla's revenues were up approximately 12% in 2007 over 2006. She also mentions a few matters that are worrisome. Though eWeek's Joe Wilcox's predictions of Firefox's demise are premature and without a doubt require a sizeable grain of salt, he makes a good point concerning revenues coming from Google versus Google's commitment to the Chrome browser.

In October, Mozilla witnessed a surge in Firefox 3's market share as it continued its plan to decommission Firefox 2 -- and the Gecko engine that powered it -- before the end of December.

For two weeks in October, Firefox 3 claimed 20% market share, something that web metrics company Net Applications predicted might happen within a month of the new version's June release. Stalled growth, and Chrome's appearance caused some backslide, but Firefox 3's pulse is getting stronger.
