Download Mozilla Firefox 4.0 Beta 12

Mozilla has decided to release one more beta release of version 4.0 of the Firefox web browser before they start working on the release candidates. In version 4, the appearance has been overhauled, among other things. 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 html 5 and css 3 has been improved. Beta 12 includes performance improvements when playing Flash content and the compatibility of the hardware accelerated plug-ins has been improved. The full changelog looks like this:

What’s New in this Firefox 4 Beta

• Increased performance while viewing Flash content
• Improved plugin compatibility with hardware acceleration enabled
• Hovering over links now displays the URL at the bottom of the window rather than in the location bar
• General stability, performance, and compatibility improvements
