It is better now, but not working in all YouTube tabs... IDK why, but I use Firefox Nightly, maybe that was not tested in this Browser. So please include Nightly in compatibility list.

I like it

New user of a few days and loving it so far. Has practically every option I've wanted for YT. No issues yet.
A Lite version for music.youtube would be great, but that would be primarily to handle glitches with the video feature.

Excellent Extension for YouTube viewing. Has just about every feature you can think of - some of which I'd never considered needing until seeing the option. Would highly recommend to anyone who spends a lot of time watching YouTube.

I use this extension whenever I'm on YouTube. It allows me to control and tweek options so YouTube behaves and appears how I like it. It's a great extension, even though my review is written poorly. Try it and you likely will like it too.
