This works perfectly when a lot of similar extensions have failed me. The only issue I have had is that it sometimes fails to work when I open a new tab from a link, so I have to disable and enable it again for it to continue working.

When I want to make all volumes equal, I use this. Didn't encounter any problem.

Holy Shiznozzles! This works in realtime, and like instantaneous response on modification of values. I hope this gets option to maintain custom saves based on websites like Audio Compressor by vatara, but overall the finesse and visual feedback of this overtakes the cake from vatara's extension. Finally a good F***ing range compressor extension that actually does what it says!
