Blocks everything and then some, if you use its advanced blocking features. Fantastic

Very good, updates & adapts quickly to whatever nonesense youtube keeps trying to do as well as just being a good thing to have on all sites really.

My top three add-on when I use Firefox.

seems to be working again on youtube as of 6/26. thank you, developers, for your hard work. sorry i was so harsh in my last review, i was upset at youtube
