I can't believe I've only just found this one. It's now an indispensable part of my Firefox setup.

It's worth it just for being able to mousewheel the volume, never mind everything else!

Well done, developers.

Awesome Add-on keep up the good work!

Awesome Add-on keep up the good work!!!!

simply awesome!

I give it 4 stars as was told never give any perfect as then they stop improving the product or life / great program only thing not sure if me , but at times wish I could just start YT in regular mode for work related- research stuff and not have to keep switching back . Probably a way to temp disable just to lazy to find it if is then by all means use it great stuff

Excellent add-on that enhances your YouTube watching experience!

Very useful Extension

Awesome!!!

The default setup is a little bit too much in the way

GOOD!

Very good extension, will be better with a possibility to have details on the youtube channel and the video (statistics).

Simple, easy, quick, and free. What more could you ask for?
