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.

Very useful. Thanks

Very useful

saw this on a hasan stream and it looked really useful lol, definitely a necessity for just about everyone, and super user friendly! UI could use a bit of work, but definitely still functional.

Work 600% as described!
Thanks for this Product.

Does what it says!

Have no fear, if your professors mic volume on a recorded lecture is very low, this can save you!
