Does what it says on the box, but for some reason it made tooltips not function at all in Firefox.

Trash dont even boost the sound or the bass option doesn't work...

NOT RECOMMENDED! This extension mutes my volume. It took me forever to figure out what was wrong with my speakers.

used on streaming site, enabled, no sound, have to restart browser to get sound back

Simple, easy to use, and it actually works!

Perfekt!
