Funktioniert sowohl auf Youtube als auch auf Twitch hervorragend.

works well on the sites it's allowed to except for twitter with mono videos, the mono convert feature doesn't work for me. no sound no matter what.
(i'm using 7.1 surround in windows)

I've been having trouble with YouTube volume ever since I got this new computer, and just installed this add-on, and it's brilliant. I love it so much I created an account soi I could write a review. Thank you so much

It was exactly what I was looking for. But the extension does not activate automatically. It's always disabled, I have to activate it every time I enter firefox... Fix it please...

The sound just disappears completely

It would be nice if i can access this feature from Right-Click menu on specific media/video, cause most of the time i don't know which control for which video on website with a lot of videos in one page, like facebook

Ok

It works exactly as intended, it has a powerful volume increase and works even over sound equalizer addon!!
I'm on Ubuntu-MATE 20.04 using Firefox 103 PPA from the distro (not a snap).

Thanks a lot developer, I very much appreciate it.

thank you, i do not know already if it works but you made this app, thank you
