excellent work !!

Does what it says on the tin. Well done.

This is the only extension that just works from the half dozen or so that I've tried. And too, it offers every feature that I could dream up with quite a few that I've never thought of otherwise. So yeah, overall this is excellent!

Best firefox extension ever.

Makes using YouTube a much better and practical experience

Great tools!

Take control of your viewer experience with this extension. I only use five extensions. This is one of them.

Didn't know I had this. So it must be good. I use a couple of the features without realising they are part of this extension.
Thank you!

Very well done.

Absolutely one of the best Add-ons for Firefox, if you're a user of YouTube. I watch more than 3 hours of YouTube each day as part of my work, and this add-on has saved my life. It is highly customizable and it can do stuff I don't even need but I love the options.
