Thought you folks might be interested in this: It’s a way to enlarge a YouTube video to the width of your browser-window. (YouTube’s player has the “full-screen” button, but that’s often so big that it pixellates out.)
This works great in firefox at least. Just make a new bookmark, and paste that code as the location, and hey presto. Any youtube video you’re watching you just click that bookmark and it’ll redirect you to the fullscreen version.
