Can we get html 5 video support on Firefox now?

I heard that Firefox 20 supports HTML 5 h.264 video on Windows now, by passing the video decoding off to the OS. So we can do html5 video out of the box on Windows theoretically.

I know h.264 support been made a default in nightly builds, but I think you still have to manually enable it in the most recent mainline release. I imagine the engineers probably won't make any changes until it's enabled by default for the average person that isn't digging into dev builds.

Check this out if you want to enable it.
