Needs updating. Stopped working on recommended video list in right-hand column - now only works on Home and Trending pages (neither of which I use). Presumably youtube made some changes that broke it. Now effectively useless for me. Hope they make the necessary upgrades.

Doesn't work. Rules are deleted every time you close the browser.

What I entered cannot be kept. The blocked ones keep showing up.

"X" button does not show up at all

Doesn't work ..

Doesn't work most of the times. Sometimes it does, sometimes it doesn't. I just wanted to block videos to certain games that I wanted to play for myself without getting spoiled by some videos (titles and such).

Barely works, completely stopped allowing me to block channels or videos and I was still able to access so-called "blocked" channels. Rubbish.

does not work with classic layout
otherwise would probably be 6+ out of 5
