It works when I lock my phone or quit my browser, but for some reason playback stops after around 8-10 minutes.

Does exactly what it's supposed, without a fault - perfect!

Perfecta.

Kuch nahi chalaa

Didn't work.

Works perfectly! I can save battery without having to fork out $10/mo. just to utilize a function, while NOT really caring about the other "features" of YouTube-Red

It works great and YouTube playback is not interrupted when you switch to another card 👌🏻
It already works on the latest Firefox 82 for Android! ♥️

Działa świetnie i odtwarzanie na YouTube nie jest przerywane po przełączeniu się na inną kartę 👌🏻
Działa już na najnowszym Firefox 82 na Android! ♥️

Great add-on just what I wanted huge respect to the people responsible for making it but I have to report an issue. Since I started using new phone a couple days ago YouTube mix playlist won't work when screen is off. I use honor play Android version 9.1.0.331 and Firefox version 68.1.1 add-on version 1.5 . I tried clearing cache from Firefox, clearing data from Firefox then reinstalling add-on, just removing and installing add-on, reinstalling Firefox nothing works. Please help 😢😢😢.
FYI: while the screen is on everything works fine either when I'm in another tab or in another program.
