Es fantástica, funciona a la perfección con Firefox para Android.
Justo lo que buscaba desde hace meses. Ya no es necesaria una suscripción a YouTube Red :3

Very useful: I can finally listen youtube videos and playlists with the screen locked!

Thanks.

This extension is one of the main reasons why Firefox is better than others

Thank you very much for this addon, Firefox! Now I can listen to lectures on my phone, without the need to keep the screen on and drain my battery. YAY!

That's exactly what I was looking for. Thank you!

I like it

Firefox is the best..

good
