Very effective ad blocker.

it works. sometimes it works overtime. as in, blocks things that shouldn't be blocked, so some sites load incorrectly or straight up don't load at all. alas, this extension is the only one among the popular ones which does not open annoying "give us your money" tabs when updating, so I won't stop using it. still, I do hope those false blocks will be fixed.

BLOCKS PLAYBACK OF ALL VIDEOS ON YOUTUBE.☹️😡🤬
