Hi With Firefox 4 as the default web browser in Fedora 15, users will now be able to access a wide variety of content in YouTube without any need for a third party plugin or patent encumbered codecs http://youtube-global.blogspot.com/2011/04/mmm-mmm-good-youtube-videos-now-served.html "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. As we work to transcode more videos into WebM, we hope to reduce the technical incompatibilities that prevent you from accessing video while improving the overall online video landscape. Transcoding all new video uploads into WebM is an important first step, and weâre also working to transcode our entire video catalog to WebM."
