This is the only addon that work best blocking YouTube ads.

Too much permission !!

Turkish Review - Gerçekten bir tarayıcıda olmazsa olmaz bir eklentidir. Zamandan tasaruf etmenizi sağlar ve saçma sapan istemediğiniz reklamlardan YouTube'ta kurtulmuş olursunuz.

Fabulous FF addon. No more annoying YouTube popup adds. Thanks

Generates CONFLICTS with player!
Generates ERRORS loading YouTube pages!
Disables players preferences, such as "Loop Video" and "Playback Speed", i.e. resets all to default after playback finished.
Does not block ADS !
Complete CRAP !!!
I wonder how Mozilla manage giving "Firefox Recommended" badges??? Maybe just SELLING with no any inspecting extension's performance?!

great extension

Its pretty good for normal videos but it would be nice if we could turn it off while watching certain YouTube channels we want to support

Flawless.
I just test it to open a video that have ad on when I open it and add this.. and then it's just disappeared from existence.

Awsome
