What is YouTube no Buffer (no autoplay)?

YouTube no Buffer (no autoplay) is a comprehensive Firefox extension designed to stop auto-buffering and auto-playing of videos in YouTube's HTML5 and Flash players. This helps to save precious bandwidth, limit simultaneous buffering of multiple tabs and enhances user control over YouTube's playback. Features support for "/watch?v=", "/user/", and "/channel/" pages among others. Note: the add-on does not aim to stop YouTube players from playing next tracks.
