Firefox 4 has now been officially unveiled and is ready to download in a Beta 1 release. The Firefox 4 Beta includes an updated Windows interface that’s sleeker and easier to use with Mac & Linux versions for the new Firefox 4 browser following soon.
The new Firefox 4 supports WebM format allowing you to watch open HD video in conjunction with HTML 5 video. Mozilla have also made the tabs a visual priority and included a new Add-ons manager helping you to discover new plugins and manage them with ease.
Firefox 4 also tightens its security fixing flaws in some web standards that allowed bad guys to snoop around and expose your browser history.
Other features that are in the pipe line include Sync, that will synchronize your settings, passwords, bookmarks, history, open tabs and other customisations across multiple devices so you can take Firefox with you wherever you go. Together with new privacy controls, Lazy frame construction and hardware graphics acceleration.
