You’ve probably heard it elsewhere first but the 5th beta release of Firefox 4 is now available to download, test and generally freak out over.

There’s plenty to coo over in the release including a new audio API (video below), menu adjustments & improved security muscle.

Download, as ever, available @ mozilla.com/firefox/beta/

Alternatively, for those who demand it be installed, a PPA is also available.

Mozilla demonstrate Firefox’s new audio APi. Or something.
