I honestly couldn't use youtube without this extension anymore. I don't even use many of its features but to be able to ctrl + mousewheel to speed up or down a video on the fly without having to click small icons is simply great. I also really like the automatic pause of any background video when you start a new one.
You can enable or disable any feature you don't want which is great.

Great!

Wow. Juste, super. On peut personnaliser notre Youtube comme on veux et on peut avoir les pubs QUE sur certaines chaines. Exactement ce qu'il me fallait. Merci beaucoup !

Nice. Works perfectly!

Top Add-On!
Die Themes und die Lautstärkeäanpassung per Mausrad möchte ich nicht mehr missen.

Please consider adding the ability to change the *Keyboard shortcut* for Cinema Mode.

Alt + Shift + End is mission impossible on my laptop... :'(

Love the addon,
Thank you! :-)
