Firefox 4 Beta 7 is available now, and it has received a speed boost “for rendering web pages and interpreting webapps and games.” The new browser is compatible with Mac, Windows, and Linux systems. Video demonstration after the jump.

In addition to the raw code and horsepower additions, Mozilla also notes the inclusion of hardware-based graphics acceleration in this beta, along with more obvious integration of previous experiments like Sync, Pannorama, and App Tabs.
