Firefox 4 , is one of the best internet browsers , if not the best ... and thus knowing its limitations and what it can do its good for you. A news page article said that "Nvidia and Firefox 4 announced 3 HTML5 videos on Youtube , available exclusively in Firefox." "Starting with Firefox 4, WebM videos encoded with 3D data will be displayed in high-quality stereoscopic 3D using NVIDIA 3D Vision hardware. 3D hardware has moved from movie theaters and into people’s homes through TVs, laptop and desktop machines. 3D video games are in wide use today. And consumer hardware that’s capable of capturing 3D photos and videos is starting to come onto the market. In fact, there are several thousand 3D videos available today on YouTube. And starting today YouTube will transcode and play these videos into the open WebM format with 3D for use with their HTML5 player. This feature is currently only available in Firefox 4. It’s our hope that other browsers will follow and add support for 3D HTML5 video as well." source "blog.mozilla.org"
