"No audio/video found in the current tab. Note that some websites do not work because of cross-domain security restrictions."

Translation: Only works when it feels like working.

Trash

doesn't even give an option to change the volume

Audio Equalizer is the name of the addon you're looking for. It's like this one but it actually works outside of youtube. The interface is worse but at least it works at all.

all my videos need a -0.75 pan. but EVERY video I open, i have to set that manually?

this is more anoying than the audio problem haha...

It does nothing

Not only does it do nothing, but even touching a slider will cause complete audio loss. The only way to restore audio is to disable the extension and refresh the page.

Well what can i say other then it doesn't work! 🫤

This add-on only reduced the sound or returned to sound that is too soft for me to hear comfortably.

I have to give this one star because I have no idea how to use it and there are no instructions here. I'm more than competent with computers and I use Youtube very regularly, but after installing this and restarting Firefox, there's absolutely nothing new on Youtube video pages to interact with to use this addon.

re-sets itself back to zero.

The sound just disappears completely

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
