Good extension, does what it says.
Few improvements suggestions:
A. Enable auto play next song (I believe Firefox blocks the background page from redirecting)
B. Make this add-on appear when searching for YouTube on FF add-on page.
C. Enable only audio download during background session (to save bandwidth)

Give this guy a medal!

Works fine.

Awesome

it does what it is supposed to do.

I was having to use the desktop site for this, now I can use the mobile site again.

Τέλεια! ευχαριστούμε Mozilla!!!
