I just downloaded Firefox to try it out a bit so I can compare it to chrome which is what I use tried to play a video on the site here in HTML5 and Firefox gave me the finger pretty much. Whats the deal? I play HTML5 stuff with chrome with no problems. Edit: Also, sorry...this should have been Off Topic.
Because the site uses the h264 codec, which firefox doesn't support
GB should switch to WebM so we can view them in a free way.
But then Safari and IE9 users would need to install 3rd party software. Also, no more video on iPhones. Google has claimed they will remove h.264 support from Chrome for over a year now, but has never followed through with it. Mozilla is getting tired of waiting, and it's looking more and more likely they will support h.264 in the future.
@ZimboDK: But I don't care about Safari, IE9, iPhones, Chrome or even Chromium (there are uncertainties about the licenses of some of its source code) and neither should Mozilla. Once you're using them, you've already lost your freedom. H.264 is a patent-encumbered format that shouldn't be supported. If Mozilla decides to do that, forks will keep it out.
The whole HTML5/video codec/Flash story is long and complicated.
HTML5 actually doesn't even say which codecs should be used by browsers (although the initial draft did), so technically the question is a bit flawed. Firefox does support both webm and ogv codecs, however. Read here, nice and clear explanation on the topic:
