As of 01.02.2026, YouTube videos wouldn’t play in the background on Firefox mobile. This extension fixed the problem perfectly. Highly recommended.

Wow, it just works. I can switch tabs or use other apps or lock the phone and yt is still playing. The funny thing is that ggle AI showed me this addon :)

Работает до сих пор.

Was running into problems with browser-based videos not playing in the background. This popped up as a suggestion and I tried it with some hesitation. But, lo and behold, this fixed the problem right away.

Sometimes works, sometimes doesn't

You are a life saver

It plays in background, but often doesn't load the video in background.

Meh. More miss than hit

wow this works. thanks. Now I can turn on my phone display while m.youtube plays in BG
