Download Mozilla Firefox 4.0 Beta 2

The Mozilla Foundation has released the second beta release of version 4.0 of its web browser Firefox. In version 4, the appearance has been overhauled, so that it can be used faster. For example, the tabs are now placed at the top and there is a Firefox button under Windows Vista and 7, as is also the case for Opera. Furthermore, there is full support for WebM, WebGL and multitouch displays, and support for html5 and css3 has been improved. Beta 2 is available in a wide range of translations, where beta 1 was only available for download in English. In addition, the tabs have now also been moved upwards in the Mac OS X version and several performance improvements can be seen.
