Stop Autoplay for Youtube™

If you have ever opened a bunch of videos in the background, you will know how annoying it is when they all start playing automatically. With this extension you will never have to worry about videos auto playing in the background. Plus, they will auto buffer, so no annoying load-spinner. *Note*: This does not work with playlists, as YouTube™ itself offers an option to disable auto playing the next video for those! Difference to "Stop Autoplay for Youtube™ Extended": This extension here does not play videos automatically. However, it doesn't stop auto play when you have the tab in foreground (so it doesn't annoy when watching a few videos in a row). Changes: 4.0.6.3: Fixes not stopping on Channel pages and prevents stopping the video when the internet connection is slow 4.0.6: Fixes stopping when seeking / clicking play for the first time 4.0.5: This version fixes the "Video automatically plays when switching to the tab". I am sorry that this didn't work correctly. 4.0.4: Right click on YT Video -> Loop is now supported. 4.0.3: Fixes an issue, where videos would automatically stop playing on tab focus; Fixes: Prevents stopping fast-forward (Thanks for the bug report!) 4.0: Updated with fixes, higher performance and to counter an experiment by Youtube™ which automatically plays the video.
