That's exactly what I was looking for. Thank you!

Pretty useless. Works for a few minutes but then the video pauses again. Very annoying to go back to youtube to get the video playing again. I have a samsung s7 edge and i was using the latest version of firefox.

I like it

It stops playing after some time when screen is off.

Firefox is the best..

good

It works, IT WORKS!! Thank you!!! :)

Great add-on. Cheers!
