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!

the best

perfect for people that like to watch a lot of you tube.

Excelente, hace lo prometido.

Fantastic add on

It just does one thing, and it does that thing well. This will, no matter what you use youtube for, be more convenient than youtube without it. Use it.

Very Handy tool.
Cinema mode is one of my favorite options.

Great!

Great simply great.
