Google have been trying to screw us by shoving YouTube Red in our throat for an "amazing future" play while the screen is off, even though it's even available in my country. Without you I would not be able to play video without wasting my battery again.

Let's you play YouTube videos in the background in the Android app

Yet another reason to love FF! This solved my YT problem! When I first DL'd FF, YT played great in the background, but then would stop. So far, this extension has enabled continuous playback of music or documentaries when I play my games...I just installed, so we will see how it stands up over time!

Works like a charm. Thanks! :)

Background playback had stopped working and this add-on fixed it!
