Works extremely effectively for youtube, have expericenced a few hiccups but nothing major. Not persistant on every website it functions with, so may have to adjust audio repeatedly. it is persistant on youtube though - only needing to adjust audio if the individual video is too quiet or too loud. Also doesnt work on every website, but the description already tells you that.

this addon only works for one video at a time so it needs to be reset for every episode of a quiet ass show on netflix, tedious and therefore useless

All I need to do is click the icon, and the mono checkbox, and bam, unwatchable video is now watchable! Great add-on for anyone who hates videos with terrible panning.

Simple and works, open source, less permissions than others and no ad injecting. GG

Amazing work

"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

It works

doesn't even give an option to change the volume

I use it a lot, but honestly, i can't hear a difference between a 2.0 gain and a 5.0, it's like, just moving the gain up you get a significant audio boost, but moving it up more it's still sounds the same.

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.

Works exactly like expected. Bonus feature: Gain can be adjusted greater than 1. Means you can literally amplify the sound

Perfect!
