love it, does exactly what I want, I would highly appreciate if the extension icon were white, since the current dark icon is near impossible to see when a dark theme is used.

GOOD JOB MATE! Highly recommended using Firefox on Lenovo T420, i7, 16gb ram, and 1tb Samsung e860 ssd

did the jop greatly

works great!! no issues so far using win7...

This is greatness. I can hear...

that shit just doesn't work

So f*cking good. Love it <3

The Extension works perfectly however when you activated it will reload the video, also you need to select the volume again. That's why the 4 stars, from there works like it supposed to be.

So simple and efficient! I love that it's TAB-SPECIFIC!! Great job!

Its a brilliant sound booster. I was always looking for something like this on firefox. Though chrome has sound boosters, I didn't find any decent ones in firefox. But this one works brilliantly!!!

Excellent. My Mi Horizon Laptop was having extremely low sound...this worked like magic...truly wonderful

Very nice, but would be much more better if you can set default volume via settings.

Why did you removed ctrl+shift+V short cut??
I only can give you 1 star for this add-on so far.

When active, YouTube video's speed doesn't work.

It's there when you need it. Works beautifully and quickly. Highly recommend
