YouTube has just announced that they will support HTML5 video that allows one to play hosted videos in modern day browsers without requiring Adobe’s Flash player to be installed in the first place. To take advantage of this new feature, you are required to opt in to the HTML5 program on TestTube. Needless to say, Google’s Chrome browser supports this alongside the other traditional big hitters like Apple’s Safari and Internet Explorer with the Chrome frame installed. Glaring omissions would be Opera and Mozilla’s Firefox, even when both browsers play nice with the HTML5 video spec. We wonder why this is so, and hope that a future fix would remedy the situation.
