Works really well.

Although there have been rare occasions where the tab goes all white seemingly randomly, but the video still plays. When I move my mouse, it either returns the tab to normal or reloads it. Other than that, the add-on is fantastic!

I use this every time I em in Youtube and enjoy the quality.

Simply amazing...

Youtube would be unbearable to use without this extension. So much crap added to our screens now without it!

Just makes Youtube so much better, cinema mode helps me focus on the video I'm watching and being able to set default settings for vids are so nice, so you don't have to do it every time you are viewing something on youtube.

The best thing I like about this extension is the feature to be able to set default volume, screen resolution. Another one that I like is being able to loop between a particular part of the track.

My favorite thing in this extension is the scrolling on the video for volume and when i scroll to see comments I can still watch the video! At this point, I can't deal with watching videos on other computers without this extension :/

Elle est très pratique, offre des disponibilités utiles pour utiliser au mieux son lecteur youtube. Très bien.

Best Youtube extension for Mozilla Firefox so far ! Happily using it !

Great extension, thank you!

Excelente, hace lo prometido.

Fantastic add on
