YouTube Looper

When looping a YouTube video, YouTube will stop looping it after some time. This extension adds a custom loop button to allow you to loop videos indefinitely. To use this extension, click the loop button beside the fullscreen button in the video player (as seen in the screenshot). DO NOT use YouTube's loop button. The button will be green when looping is enabled, and red when it is disabled. If the button is not showing up, just refresh the page and it should appear. (And of course, make sure the extension is activated).
