very good add on. i use it all the time!

Doesn't work at all for me

molto pratico ed efficace...

Working fine, efficient.

LOVE BIG VOLUME BOOM!

Simple, and doesn't cause memory leak like the alternative.

it sets volume to 100% every time i restart firefox; useless for me

just whati was looking for, the adio does not get destorted the more you boost it. also... pp. but still good

VERY VERY GOOD

it's awesome!!! what? it's really great you can get the volume really high!!!!!! WHAT?!??! i give this addon 5+ stars! TURN THE VOLUME DOWN!!!! what? NO!!!! :P

Отличная вещь, часто приходится пользоваться, своё назначение оправдывает.

It WORKED! THAAAANK YOU!

its amazing but i wish to put an option to automatically volume up
