Youtube has changed the design. Now this extension does not work. It is sad.

the best add ons known to mankind

No longer working on FF 115.7.0esr nor The latest waterfox. This is troublesome as with means it no longer works on Windows 7!

Works as expected, does what it's supposed to do and has nice and tidy settings.

Brillaint extension for FF. It just needs more more mode. An Auto Full Screen after clicking on a video to play.

Best Add-on ever. The speed control is outstanding, I love playing videos at 10x just to enjoy the content without taking up too much time. I never YouTube without it!

best addon, thanks for bringing it back

A must-have extension IF it worked consistently. Right now it works like 60% of the times I click on a video which defeats the purpose of having it installed. Very unfortunate.

I was sad I couldn't find this extension on Firefox. I've been using it on Chromium for a long while now and I'm extremely glad it's back here too now! I think this is one of the best, convenient and full Youtube enhancer extention out there! It's a must have, truly!
