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.

App works for browser Twitch, and I'm super thankful because my comp volume is cranked just to hear a lot of streamers. Wish the gain could go up a little higher still though. But that's because Twitch/streamers, not poor design.

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

Does not work with different playpack speed for YouTube

Installation aborted because the add-on appears to be corrupt.

SoundFixer works well on non-cross-domain sites so I can hear what's going on through my not state of the art speakers. Unfortunately, when I leave a site after using SoundFixer, the volume level is reset very low, so the next time I go to a cross-domain site I'm up a crick and can't hear a thing.

Doesn't work at all

a youtube video was only playing on the right side, thank god for the pan setting, i moved it a little bit to the left and now it plays on both sides :P

My sound was too quiet. This add on fixed it! Just what I needed.

i watch a lot of jerma streams and he always has his microphone incredibly low so this is a god sent!!!

Works excellently with no YouTube issues. I also have Enhancer for YouTube which may or may not have helped it work correctly.
