I know that Mozilla has taken an ideological stance against H.264 video, but I don't agree with it. (And I think I paid for a hardware decoder inside my graphics card anyway?)
Is there any way I can force Firefox to play H.264 videos? Is there a hacked version that includes support for it? A plug-in?
Chrome's extensions aren't as good as Firefox, so I'm not ready to switch, but videos run so much smoother and more efficiently without the Flash layer in between.
