I am writing a second review for this ABSOLUTELY FANTASTIC extensionbecause - I have it installed on Chrome, and have switched back to Firefox for several reasons. The FIRST thing I looked for was THIS to make YouTube sudn amazing in earbuds from my laptop. It is simply top notch, and perhaps even more than mouse gestures or auto copy, it's essential IMO. It just WORKS. Please support this developer in any way possible. It NEVER glitches, it's easy to configure (pinned to browser bar) - sound quality is NOT distorted unless your other sound settings are pushed (pregain, iput volume, etc). Simply GREAT. Thank you so much.
