Very handy to have from time to time. Occasionally a random video will have it's audio balance set way too low and this is a life saver.
NOTED BUG: I use brain.fm for music and for some reason brain.fm won't play with this extension active. I tested each of my extentions independently and for some reason this one gives it trouble. I've reported it to brain.fm as well. LMK if there's a more appropriate place to report this bug.
