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.

I love how it stops autoplay, as well as the multitude of themes it offers. Great plugin.
