So good that I actually wrote something here.

This extension is amazing and lets you customize how YouTube works and looks. Anyone that uses YouTube on a regular basis really needs this extension, because it will make things so much easier for you. Thanks a lot to the folks who developed this extension and to those who update it.

вообще не работает! It does not work at all with Tele2 which is blocking youtube in Russia.

Works about 10% of the time. Very rarely shows any of the controls it's supposed to

super

Very good extension, especially like the volume booster since everything seems to be quiet at 100% volume on my computer but half the time it doesn't even appear.

TOP NIVEAU !

I'd love some minor tweaks, like being able to change a bit more of the contraste, even some sharpening or smart blur, stuff like that.

Excellent Add-on - Developer keeps the plug-in updated and its one of the best YouTube enhancer plug-ins of its type.

i love PiP
