Very good and usefull add on.

Scrolling to adjust speed is the best when watching follow-along tutorials. Also being able to read comments and have the video still visible is great.

EXCELLENT!!

Really great extension.

Additional features a long time coming

Best youtube add-on.

A great add-on. Features that should be, by default, a part of YouTube.

great addon works as advertised

I truly enjoy the features this adds to YouTube, especially the small video window when scrolling down. I'd love to see a feature to hide watched videos inside of subscriptions, as well as the ability to watch a playlist in reverse order.

Great product. Feel crippled when I try to use YouTube on a different browser. Highly recommend.

Very useful addon. After installing firefox it is the first thing i install along. Thank you!

Fantastic, every YouTube user should install this!

A great little add-on. I find it quite useful.
