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.

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 :)

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 ;)
