What licensing fees? h264? Well I'm not entirely sure how, but lots of FOSS projects support h264, most prominently x264 and ffmpeg, and software building upon them. Just do it like they do.<p>... or just use system codecs.<p>besides I'd guess Google would be happy to have h264-supporting Firefox, and end this farce, so getting some kind of sponsorship from big G wouldn't be that improbable.
