Codenamed as Namoroka, Mozilla’s latest release Firefox 3.6 Alpha 1, has been revealed. Web application developers and testers who intend to test and have a feel of this latest Firefox browser can check it out. This new Firefox 3.6 Alpha 1 is built on the Gecko 1.9.2 platform and various new features have been added. The most significant change in this release is the speed improvement to the TraceMonkey JaveScript engine. The new Alpha 1 also presents an incredibly fast start up and amazing responsiveness throughout the application. The long awaited visual tab previews which are supposed to appear in earlier versions have finally come along in this Alpha 1 version as well. In addition, other new features include new aded CSS3 properties (background size and gradients for background images) and chromedir attribute with a pseudoclass.

Web developers who intend to try the new Firefox 3.6 Alpha 1 can read the full release note via the link here and download the Namoroka for Windows, Linux, and Mac OS X in English accordingly. General users of Mozilla Firefox are, however, not recommended to use Namoroka Alpha 1 as this release is purely for developers and testers.
