SoundFixer
Helps you fix annoying sound problems on sites like YouTube: audio in one channel only, too quiet or too loud.
(Unfortunately, this extension does not work on all websites because of cross-domain issues — but it does work on YouTube!)

It adjusts audio in one channel only, reduces excessively loud volumes, and boosts quiet ones, significantly enhancing your viewing experience.

User reviews
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
