One of Its Kind Rated 5 out of 5 stars
This is the only addon that will work for you, if you are watching a lot of video streams. It works on virtually every video out there.
It might have some small glitches here and there, but author is willing to look at every problem and try to solve it. And I want to assure you that after a while you will stop noticing that small switch icon showing up in unexpected places (like, for instance, flash menus). :))
