Is there a HTML5 extension for watching YouTube videos in the new Orweb browser for tablets, like used to be with the Bundle for PCs, all the while offering your computer to the ongoing Tor traffic?
If you want to experience with HTML5 video proxied through Tor, you can try the development builds of our new Firefox-based secure browser, named Orfox.
This is development/debug grade technology and has not been fully tested!
