i didn't really need the 600% boost and the UI is funny but after trying them ALL, this is the only per-tab volume controller that works. And it works WELL! Thank you for achieving exactly what I was looking for, the name is deceiving but the description for the extension explains it all. This is a great and powerful tool and the ONLY volume controller on the official firefox addon marketplace that's worthwhile.
