The writing's on the wall, though, so you can just use something like MediaElement.js' Flash fallback until Mozilla ships OS H.264 support for other platforms. That's a much better situation than having to double your media transcoding & storage costs.
Firefox doesn't support H264, but it can offload the decoding to the OS. So if your OS doesn't have it, it won't work. This affects Windows XP, which still has substantial users.

A huge part of the problems with the web are people playing politics with technology.
Leave the highly common hardware accelerated that's the _only_ one all browsers support alone.
VP8 can beat it on technical grounds.
Of course, without b-frames, VP8 can't beat squat.
As far as I remember, Firefox only supports H.264 on Windows. So it's not quite supported by all browsers.

Firefox supports H.264 on Mac via the QuickTime plugin.
Firefox supports H.264 on Linux via the Flash plugin
Flash has historically always been used to deliver H264 to Firefox, though. That's not quite the same as the browser supporting it in <video>.
