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!)

SoundFixer: The Ultimate Add-On for Fixing Sound Issues

SoundFixer is a Firefox add-on designed to alleviate common audio problems associated with streaming video sites. It adjusts audio in one channel only, reduces excessively loud volumes, and boosts quiet ones, significantly enhancing your viewing experience. However, due to cross-domain constraints, it may not work on all websites. But, rest assured, it works perfectly with YouTube.
