It works, zero issues, just pure QOL improvement.

Finally I can listen to audiobooks without restarting YouTube every time I unlock the phone. Thank you!

You can listen to music on YouTube with the screen off. Great plugin!!

Uso questo add-on da anni!!!
Ha solo il problema che ogni tanto tra un video e l'altro devo rientrare nella pagina, ma assolve al suo scopo!!!

Perfect.

Great for running YouTube videos in the background.

This extension works flawlessly, you can experience YouTube to its greatest potential, it allows playing in the background, even if you turn your screen off this thing keeps the music or whatever YouTube content you have playing.
It's a must have.
Thank you

Works especially well on mobile devices. "Chef's Kiss" well. If it could give this addon 6 stars, it would in a heartbeat.

Isn't necessarily needed on PCs.
