Все ок, но минус одна звезда, к сожалению :(.
Есть баг, что при активации расширения, не нажимается кнопка с тремя точками, там где скрыты опции типа сохранить в плейслист...

Worked perfectly but youtube now blocks ff from playing videos when this extension is detected.

It did work even before Youtube's recent adblock update, This addon probably might trigger Youtube's adblock though.
It's not really the developers fault for that, Good addon though.

Working well the best adblocker for youtube but please fix an issue when the adblock is on is triggering a error #2000 on twitch

Relied on this for a long time and it's never let me down. Recently it seemed to break youtube. When I reinstalled it - it didn't seem to work. There were the ads.

works just as it was reported to--oh-yea !!!
