This add-on really works! Rated 5 out of 5 stars

Since the latest Firefox update (17.0.1) it has not been possible to stop a video opened in the background from playing. I have tried out numerous other stop-play add-ons which did not accomplish this. This add-on successfully accomplishes this task. Kudos :)Request for next upgrade: Give us a way to enable playlists to play, but to stop individual videos from playing.

This review is for a previous version of the add-on (0.11).
