Hey, you. Yeah you, with the android phone. What you're looking at right here is the best workaround for playing Youtube audio in the background, including while using other tabs, apps, or even with the screen off. And it's only a click away. You're welcome.

Perfect.

Absolutely necessary, it's awesome.

Works so well, thank you!

This add-on does something so basic, I wonder why Mozilla just didn't add it into the browser as a toggle.

I would love to say thank you to the author of this addon as it saves the day and not the only one.

Working again with the latest Firefox. Great work!

Outsranding addon and great support. Allows listening or running video while multitasking. Was very missed when firefox first rewamped and lost it, was considering rolling back, must have.

Semplicemente fantastico, praticamente l'unica opzione funzionante per utilizzare YouTube a schermo spento!

Zainstalowałem na Firefox beta i działa YT w tle.

This is one of the essential add-ons to differentiate firefox for android from other browsers.
I doubt AMO's sense for not enabling it.

Lifesaver!
