Description
-----------
If you've ever opened a bunch of videos in the background, you'll know how annoying it is when they all start playing automatically.

With this extension, videos only start playing when you actually switch to tab which has the video in it. You'll never have to worry about videos autoplaying in the background. Plus, they will auto buffer, so no annoying load-spinner.
