You did add the feature to a degree however it is very low frame rate gets a slight zoomed in and the quality is extremely low.

Thanks so much for making this extension. I gave it a solid 4 stars. To get 5, it needs to work on the Homepage and show smoother video. It's a little choppy but hey, I'll take it. Thanks!

Would be much better if worked in the homepage. Not much to complain other than that.

Does not work. PLEASE update! ;)

Doesn't work.

I am tired of it constanly breaking (Firefox 59.0.3x64) ! Is there any replacement which updates more frequently?

Очень даже работает....можно оставлять. FF 59.02 (64)
