Request: Allow for negative gain.

Some sites are substantially louder than others, The ability to go into the negative to decrease the volume of certain sites that don't have volume control would be a great addition, hopefully something simple.

Okay this functionality already exists on sites like Youtube and Facebook by setting a value less than 1. These sites are probably what people are most commonly using this for.

For some reason, Google Meets and some other sites it gets a little quieter but at 0 gain its still louder than most things. Its almost as if there is a gain pre-applied by default on these sites? These sites don't have their own independent volume control and adjust only from the system volume.

Uh… Google Meet and other voice call apps shouldn't work at all, as this addon is designed for <video> / <audio> players only (#63)
