Been using this for a few years now. Improves the experience and usability far beyond what you get from 'vanilla' YouTube – it's genuinely become a necessity for me on any browser.

Excellent extension, it does what it says and much more~

unfortunately cannot recommend it, it's a great addon, but each update breaks something basic and you gotta wait a certain period of time 'till they fix it, they will... eventually, but it's still pain in the ass so it might even be easier just use default youtube, cuz that's pain as well however, at least you can count on basic features to work every time you watch something and you don't have to wonder wtf is going on so if you use this and something doesn't work, blame this addon probably

Great functionallity! Completely stealth and fast responding to all incoming ads!

very useful addon for youtube controls, slow-fast playback.
and can now also show dislike count :)

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 ;)
