Very useful

Very good, i would reccomend this to sound lovers

did the job

This is the BEST volume booster for Firefox! No distortion! Works better than any CHROME booster! But hey, what do I know? LOL

Works well. A small update I'd like to see is a dark mode for the panel it opens.

When you think the tab is too quiet but you don't want to turn up the volume of your pc this is the right tool

Works great! Netflix is so much better now.

This works well for me in the latest Firefox update.

Good app. Sounds clear

i love whoever made this, i have never had a more useful extension
