Do you watch too many YouTube videos? Now you’ll be able to watch more in the same amount of time! ..Or return back to your real work faster by trying out a TestTube on YouTube at http://www.youtube.com/html5. It has been working very well for myself. Now, you don’t have to download YouTube videos to watch them faster for free.
Once you are at http://www.youtube.com/html5, click on ”Join the HTML5 Trial” near the bottom of the page. Open up a NEW YouTube page, and your YouTube videos will now be played with HTML5 instead of flash. And on the bottom of each video will be a speed setting ranging from 1/4x speed to 2x speedup for your productivity pleasure.
