The Mozilla Corporation has released an advance testing version of its popular Firefox Web browser, just days after Google revealed its competing Chrome software.
The second alpha of Firefox 3.1 was made available overnight. The software, code-named Shiretoko, is at this stage intended for software developers and testers only, with the stable and recommended version of Firefox being 3.0.1.
In a statement, Mozilla said the testing version of Firefox introduced several new features, including the browser's highly anticipated support for a new video tag element introduced with the HTML 5 standard to provide more functionality around the amount of video that is increasingly being delivered through Web browsers.
In addition, Shiretoko allows users to drag and drop tabs between browser windows, improves performance in some areas and provides better integration with Windows Vista's Aero 'Glass' theme for those wanting to add extra themes on top of Firefox.
The alpha release of Firefox 3.1 can be downloaded from Mozilla's Web site.
