The early release follows a last minute RC2 revision that was released on Saturday.
Firefox 4 brings with it a slew of new features, including, most notably, a completely overhauled user interface that makes it look a lot like Chrome, but hardware acceleration and the jet-powered JaegerMonkey JavaScript engine also jostle for center stage. In true Mozilla style, Firefox 4 also brings support for many emerging standards, such as HTML5, CSS3 and WebGL. Finally, there are neat features like built-in Sync, restartless add-ons, and workspace management with Panorama.
