It don't work in zoom meeting inside the browser

i have the youtube+firefox bug combo where the sound volume always is maxed out no matter what. This addon claims to work on youtube. It doesn't work, on youtube or anywhere else. Absolutely pointless, and it requires the permission to check on your browsing activity.
How it managed to get a 5 stars rating is beyond me.

Is useless, as the setting resets even on page reload.

Doesn't work at all

Youtube playback speed control does not work if this plugin is installed, so it is completely unsuitable to me as well as many others.

Can't increase video speed when using this extension.

It suddenly stopped working without a warning or anything

Just a manual gain slider. No limiting or auto gain control.

No hace nada en automatico, para cada video tienes que subir y bajar la ganancia, es lo mismo que subir y bajar el volumen tu solo sin la extensión.

No "reset default" mode.
