Yet another reason to love FF! This solved my YT problem! When I first DL'd FF, YT played great in the background, but then would stop. So far, this extension has enabled continuous playback of music or documentaries when I play my games...I just installed, so we will see how it stands up over time!

Works like a charm. Thanks! :)

Background playback had stopped working and this add-on fixed it!

fine

Excelente!!... Transcendental y básico!!... Sin esto un smartphone solo es un trozo de piedra aburrida!!..

j'aime firefox navigation trop,par ce que trop rapide et bien résultat,mai je manqué de téléchargé des vidéos et regarde sur frx merci!!

Works perfectly! This is really amazing!
