It has worked well, but in Incgonito mode (I haven't tested normal browsing mode), ads appear on YouTube videos as a blank, white screen, but so far they have been skippable instantly...

Очень хорошо блочит рекламу кстаъ

It blocks annoying streaming video ads. Great!

The gold standard by which all other ad-blockers should be judged.

I know quite a few people that still do this day complain of ads on youtube and other sites and are still not using this addon! I recommend it highly, never fails!
