the adremover in chrome brower is much better than this one,i can't watch the vedio with this plug-in opening

It seems that this plugin no longer works well. An error message appears before each Youtube video.

Gives error "An error occurred. Please try again later. (Playback ID: W0g0gZzmmrSHTLPM)
Learn More" instead of blocking ad videos.

Conflicts with twitch, when enabled - twitch raise error 2000, when disabled - everything is ok.

Used to do what's on the tin, recently has started to prevent playback. The addon hasn't received updates in over a year, so I imagine that's what broke it.

Just added this extension today to Firefox on Mac running on High Sierra, turned on a Youtube playlist I created which was filled with ads at the start of every video, and not one ad appears now, it's almost too good to be true
