just recently installed this alongside fire fox to test ad blocking capability since youtube has initiated war against fair use content blockers preventing our pc's from being infected. just tried youtube and it DOES WORK, though it will give you on some ads a black loading screen, in other words it does play the add but you get no audio or video playback so in a way it skips and mutes any ads. works better as a tempory alternative compared to ublock origin. and this version does not get blocked on youtube. so ignore tenchcoatcraig's comment, it works just slightly different.
