Quietube - Youtube Without Distractions

Got a video on YouTube, BBC, Viddler, or Vimeo that you want to access in the classroom, but can't because DansGuardian is blocking it? Frequently, this is because the comments contain foul language and it's tripping the weighted phrase limit.

Use Quietube to strip out everything but the video! This quick tutorial will show you how to add a bookmarklet to your firefox toolbar. Then, when you get the block message (or just want to remove all the extra stuff from your page) click on the toolbar button and voila! Watch your video.
