It is very functional but sometimes video transfer is being stopped like connection lost(red line above screen on firefox) while connection is stable, or autoplay doesn't start although full content of video is reachable(gray bar is full on video frame). I guess the reason is recent firefox updates.

Bravo! Indispensable. I don't know how I ever used YT without it.

Great extension. It saves me a lot of time by blocking video ads and has tons of useful features. It even feels like a natural part of the UI.

This is the MUST for every YT user, I love it and it works for me...

Brought back the dislikes count! Unexpected but welcome feature lol

This add-on give me everything that I want to have and everything I didn't know I want to have in my youtube experience. it even restores the dislike counter ;)

Please add saving YouTube subtitle settings

Best youtube extension I've ever used, by far!
