Firefox 4 Beta Version 5: New Browser With Improved Security

Firefox has released the latest Firefox 4 beta 5 with it a couple of new features like hardware acceleration for Windows users and a new audio API. Firefox 4 Beta 5 now uses Direct2D by default to speed up page rendering. Firefox 4 Beta 5 also comes with a new security feature which enables sites to force HTTPS connections.
According to Mr. Mike Beltzner, Mozilla's director of Firefox, "The latest update to Firefox 4 Beta brings super fast graphics and incredible new audio capabilities to the Web. Firefox 4 Beta now leverages hardware acceleration to improve graphics performance for Windows users and also allows, for the first time, the visualization of audio data within the browser," he explained.

Hardware acceleration is the main feature for Windows users. Firefox 4 Beta 5 now uses Direct2D by default to speed up page rendering. You will need a graphics card supporting DirectX 10, but the difference it makes, especially for visually intensive web pages, is significant. Mozilla doesn't have an alternative to Direct2D on other platforms, since it's a Microsoft technology, so Linux and Mac users are out of luck for now. The team has said that it is looking at ways of bringing hardware acceleration to all users at some point.

Firefox 4 Beta 5 also has a new audio API. The API gives developers the ability to read and write raw audio data within the browser. It's a pretty powerful API and comes in very handy in a few specialized use cases. However, it is unlikely to make a difference for most users.
Firefox 4 Beta 5 will also support for HTTP Strict Transport Security (HSTS). This new security protocol enables webmasters to request that Firefox always uses HTTPS connections for that site. This way, in the case of a man in the middle attack, which would try to redirect you to a non-encrypted version of that site, Firefox will automatically replace any HTTP URL with HTTPS ones.
