very good

Love it! It does the needful and more without affecting the browser's performance as such.

Perfect.

Simple, effective and fully featured

Just works. Cant live without it now, lol.

I can't use youtube anymore without this extension. A must have for me!

The volume control is very handy, especially as it adds a number when changing it. Automatically pausing extra tabs is also much appreciated. The menu is unobtrusive and customizable.

Great extension. If fixes many annoying things in YT especially autoplay in backgroud tabs.

It's great. I don't usually write reiews but this is just such a great extension I felt I had to. The developer is awesome : )

fantastic add on and has made using youtube a pleasure again. Thank you for the hard work and time

The controls for background fading, cinema style viewing and the configuration tools are awesome! Will be delighted if some features as rewind were incorporated into the app.

An essential add-on for Firefox. Stable, great ui-design and an invested developer.
I didn't know I needed it before. Now I don't want to miss it.

good
