Works Great in YouTube! Rated 5 out of 5 stars
Better than Ad Block Plus, which cannot be run for YouTube because the videos fail to play, this Ad Blocker however, lets videos play WHILE somehow ingeniously blocking the annoying ads that plague YouTube more and more (especially with the crappy new YouTube layout, this plugin is everything you need and then some!)
Best of class Firefox Ad Blocker I found yet for YouTube and naturally, any other website that contains the unwanted intrusion of forced-advertisements! Now you have control!
This plugin is brilliance in action and why Mozilla Open-Source is still KING...
