Beta 3 of Firefox 3.1, which will be renamed in version 3.5 when it is finalized, is finally here. Long because of multiple delays in its development, the third beta improves the main new features of Firefox 3.1, which are mostly under the hood.

As a result, the list of changes since beta 2 appear almost monotone:

• HTML rendering engine Gecko 1.9.1, with speculative parsing
• Improvements to the navigation mode closed
• Improvements to support web worker threads
• Improved performance and stability of the new TraceMonkey JavaScript engine
• New native support for JSON

Support for new technologies such as Web beacons <video> and <audio>, the API of the W3C geolocation, the JavaScript query selectors, properties of 2.1 and CSS 3, SVG transformations and applications offline - line have already been addressed in the past.

On the other hand, it is certain now that a fourth beta that will be proposed before the browser comes into Release Candidate phase. Few versions of Firefox have received so many betas, but that has essentially provides substantial improvements in submarine which obviously require a test period extended.

Beta 3 is available in 64 different languages including French, of course. Although the download links given in the announcement still pointing to the beta 2, a simple modification of links provides access to the desired version.

Hello , I have this on the Website that Firefox 3.1 Beta 3 is the fifth development milestone and third beta release of Firefox 3.1, the next version of the Firefox web browser. While this release is considered to be stable, it is intended for developers and members of our testing community to use for early evaluation and feedback. Users of the latest released version of Firefox should not expect all of their add-ons to work properly with this beta. So It is safe to install it or not Well i might Try installing it ?

Hello, It says that While on the surface beta 3 is little different than beta 2, under the hood there are some significant improvements. The TraceMonkey Javascript engine sees both performance and stability improvements (including a fix for the bug responsible for Firefox 3.1’s delay). What is this Tracemonkey Can you Tell me ?

TraceMonkey adds native‐code compilation to Mozilla’s JavaScript engine (known as “SpiderMonkey”). It is based on a technique developed at UC Irvine called “trace trees”, and building on code and ideas shared with the Tamarin Tracing project. The net result is a massive speed increase both in the browser chrome and Web‐page content.
