Nice addon! Mostly "automatical' beeing once adjusted. It is pleasant that you can choose background. Little minus as for my self- you have to look and wait the dull steps when the player "grows" to its final size. Five stars!

--no comment-- ¯\_(ツ)_/¯ best

I love all these great enhancements to Firefox, especially the volume control within the video playback screen. It really makes changing the volume so easy especially at night when you can't see the buttons to do so! Thanks for this add-on and all the others that I have yet to discover!!!

This extensions makes YouTube a lot more functional and easier to use.

A definite improvement to YouTube. Provides great set of features and is still being updated. Haven't experienced any performance issues or lag. Control over video quality works great!

I love the new controls for the volume and LOVE popping a video and pinning it up in a corner so I can continue to read through my internet pages. GOOD JOB!!

I like the quality and the easiness of this enhanser. great thing ! Thanks.

la meilleure extension pour firefox, et surement la seule dont vous aurez surement autant l'utilité, elle est vraiment super, avec pleins d'options, et de plus elle est évolue souvent pour du "toujours mieux"
