YouTube provides nice videos with info and comments, but not everyone loves them. Comments can distract your viewing experience. If you want to watch YouTube quietly, you should add this QuietTube bookmarklet. Drag this: QuietTube to your bookmark, when you want to watch YouTube quietly, click the bookmarklet, and you will see the plain background with very rare information on the screen. Much clearer? You can now focus on the content of the clip. Enjoy.
Unfortunately, it does not work with those videos that does not provide embed options.
