Doesn't seem to work on bitchute. Seems to be always off on a new tab even if the icon shows ON (you have to off+on to activate). After bugfixing, the only setting I wish it had is the usual compressor tuning (see Audacity compressor shaping min-max gain, and delays/sustain durations if that is even configurable.)

Works great on windows 10, apparently not at all on debian 11. It just makes it quieter. That is unfortunate, because windows already has built in audio compression. But it is nice that in windows at least i don't have to enable system wide audio normalization.

I have found that sometimes sound gets too compressed to sound good. If this happens to you try turning down the level on Firefox in mixer a little. I run the player at full volume but set Firefox at about 80 but try different settings to find what works the best for you. I figure that the best setting is to turn Firefox volume as high as you can without distorting the sound by over compressing to keep the volume as near level as possible. When up-to-eleven is on it slightly reduces the volume when it compresses but turning down the volume on Firefox probably won't affect the volume unless the sound is extremely low because it won't compress the sound as much on higher level source.

Nice addon. Can you make the icon change more noticeable like for example Black when disabled green when enabled or something like that? The line thing is not very noticeable. Also I noticed that if you keep turning it on and off sometimes it will boost the volume more and sometimes it will boost it less. Could you take a look at that? Thank you.
