really simple and really useful, much needed. Audio on some YT videos are just too low

Works really well!

Sound Fixer is one of the best and most reliable extensions I've ever found for sound problems on Facebook, and YouTube. I've been using it for about 10 months, and it has not let me down. 👍👍

Rewelacja do cichych nagrań! Brawo!

Nice app

works well on music.youtube.com

Brilliant extension exactly what I've been looking for and works very well ; )
