Awesome extension for the massive amounts of youtube content I watch!

Fixes all the problems YouTube seems to refuse to want to fix.

Хорошо!

Does what it says. When I scroll down the comments, thankfully I don't miss the video! Makes life a lot easier.

It does what I expected and needed.

Excellent add-on, great for people who spend a lot of time on Youtube and want to tweak the experience.

i get to watch the video in full screen, and the volume adjustments are a big plus.

Works perfectly for me, its Web smooth sailing now, many thanks!
