About this extension

Adds an stop button to HTML5 player to prevent YouTube from buffering video

Read the publisher’s full description

Have you ever wished your YouTube player had an stop button which prevents YouTube from buffering (loading) video files when you are not going to watch that particular video? If so you can have it now! By installing this extension you will get an stop button on the right side of the play button. Pressing this button unloads the YouTube player and hence it will stop buffering videos. Note: This extension only works with HTML5 players. No button will be appended to the Flash version of the YouTube player.
