Every video on Facebook still relies on Flash though. So I'm not sure why they haven't put their money where their mouth is about it yet? Would make Facebook a lot more accessible in most cases for me not having to rely on Flash whatsoever just to view a video. I usually end up not watching a number of videos after I realize it wont let me watch them without Flash.

I wonder if they're trying to wait out Firefox on the MP4 vs. WebM/Ogg issue. They've already gone HTML5 on the mobile versions.

Facebook is migrating from Flash to HTML5 video. As of last week, they are serving HTML5 video to users running Windows 7+, including Firefox users. Firefox supports H.264 video on Windows Vista+ and OS X because those platforms ship H.264 decoders.

Guess Linux gets excluded once again? Cause they keep pushing Flash to me, even though I have H.264?
