Good but not perfect, adds some lag to page loading.

This adds features that Youtube lacks such as forcing the default playback resolution or detaching the player so you can see the video while reading the comments. Thank you very much to the developer

It's amazing, and I know the developer has put so much effort into it.
It really has a lot of cool features.

Great app!

멋진 기능에 잘 만들어진 제품. 강추합니다.

Come on i now its oppen look this things Works !!!

неплохо

application sympa qui permet de configurer youtube 1 peu plus en profondeur.jamais rencontrer de bug pour l instant apres plusieurs mois d utilisation!

Definitely a worthwhile extension to Firefox, making YouTube more user-friendly. I've only used it a short time and haven't been able to check it out completely, so for now 4 stars. I expect to raise it to 5 stars after more use if it turns out to be as helpful as it appears to be.
