I already got 23 but then I have went from 15-23 and never noticed difference in the browser. only time i ever know is when i randomly check the about menu Would love it if FF actual gets there act together and actual fixes the buggy implementation of hw acceleration though

Tried it, and was considerably slower than chrome.

Indeed. Tried chrome and never looked back.

23 should also allow x264 acceleration, (EDIT: Via DXVA2, Vista and later MS OS's.) I'll need to read up on the feature list but for example Youtube now lists it as supported under it's HTML5 beta. 🙂 (I'm already on 24b1 though but it's more of a maintenance update from what changes I've read, still a nice update but it could have been a 23.5 or something too, weird release name scheme really but most browsers now seem to use something similar to this.)

Enabled DXVA2 on Windows Vista+ to accelerate H.264 video decoding

Article says 23 in title but story is about 22, then when you click on the download link it goes to 23.

How is the Win8 support ? Previous (moth or two) old version does not work very well with it, but it could be a flash problem... But I did not have to problems with IE. The only reason why I use FF is because of Greasemonkey + TACS (Tiberium Alliance Combat Simulator).
