Firefox 3.5, which is now a very stable beta, is faster than earlier versions, and most importantly, it embraces open-source video standards and treats videos like web pages (you can’t do any of that with Flash). If this takes off, Flash video could become history.

Video and audio support will soon be built directly into Firefox, by way of the free Vorbis and Theora codecs, and Mozilla is using the opportunity to advance multimedia accessibility for hearing-impaired and seeing-impaired users.

To that end, all new videos uploaded to YouTube are now transcoded into WebM. WebM is an open media file format for video and audio on the web. Its openness allows anyone to improve the format and its integrations, resulting in a better experience for you in the long-term.

Since last week's announcement of the YouTube and Vimeo beta versions which use HTML5's element, the Mozilla developers have been defending the fact that Firefox 3.6 cannot play the content on these betas even though it supports HTML5. The reason for the problem is that the HTML5 working groups decided not to specify which video codecs the tag would support.

Despite all its advances, GNU/Linux remains weak in its support for proprietary audio and video codecs. Because these codecs are often encumbered by patents, distributions must choose either to include support of questionable legality or else exclude it altogether.
