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.

does not work for youtube on android 15. works for other sites or lower android versions

Thank you SO much! Now I can play songs from youtube during parties while someone else browses for his/her song coming next. AWESOME!

👍👍👍👍👍
