5 Things To Know About Firefox 4 Beta 9

It has already been one week since Mozilla's Firefox 4 Beta 9 browser has been released and it seems as if this is finally the one that will serve as the springboard for the release candidate scheduled for February.

Apart from the fact that the browser is available in 76 languages, the biggest improvement appears to be the complete overhaul of the bookmarks and history code which, according to Mozilla, will significantly improve bookmarking and startup speeds.

It will also come with a new, sleeker and faster JavaScript engine called Jägermonkey which supports x86, x86-64, and ARM on a shared code base; some benchmarks show a four hundred percent improvement compared to TraceMonkey (opens in new tab).

Just like Internet Explorer 9, Firefox 4 Beta 9 now performs some rendering operations using the onboard dedicated GPU using Direct3D 10 on Windows Vista and 7 or Open GL on Mac OS X. This yields faster graphics performance overall and improves things like display speeds.

Unfortunately, there are still tons of hardblocker bugs, those which will prevent FF4 from shipping. As of this evening, there were 105 in all with some like the inability to print or doing print preview from a Gmail account being show-stoppers.
