Download this add on as it just works!

I only created an account to say that this app works flawlessly and that I love the creator for this <3

Its working with Youtube and I can listen to music while do other things on my mobile.
Great work, thanks.

помогает съэкономить аккум на телефоне, о время режима прослушивания музыки в ютубе

在firefox for android 是非常棒的插件！youtube 付费版才有的功能，完全满足！可惜在iOS 设备不支持。

Thanks a lot. It works. No problem. If the video stop after screen turned off, it is your android battery-saver feature. Turn that off.

Please ship as system addon. :O Thank you!!

Yasss!

No comment I will see extension how is working
