Everybody's selfish, but Mozilla is also short-sighted ... they cannot and will not be able to have an influence on the defacto standards for codecs if they aren't popular enough.<p>This was the right time to really push for HTML5 and standards ... to push Flash/Silverlight/Quicktime out of the way. Safari, Chrome, Opera and Firefox combined have enough market-share to do that.<p>But no ... they take the same stance as Linux distros, all proprietary stuff is evil, ban it all. Unfortunately, while they have a point (H264 is not safe) ... they'll just lose users to Chrome or Safari.
