works fine on all websites except Youtube. The site runs fine if I don't use this add-on. When I do, it buffers then shuts the volume down when the video starts to play again.

es muy bueno me aumento por completo el volumen sin distorsionar el audio

Something I never get to say: It does what it claims to do in one click and one drag. It has no frills, no extra clutter, it's exactly what I went looking for. Only thing I'd like is a couple more shortcut buttons (like the 100% one) for 200% or 150%.

Update: To anyone who says it isn't changing, make sure that you're on the tab that you want to make louder/softer and that the media is actually playing when you move the slider.

Works just as intended.

I just added it and it seems to work as it promises.

love this addon

Ne marche plus ? Ben alors une étoile !

Fixed my laptops low sound issue. Before I could hardly hear a thing now I have to turn it down.

Simple, easy to use, does what it says it does. Easy 5 Stars

Perfect as it its. A volume slider & booster that works amazingly!

Genuine life-saver. Perfect for people like myself that have hard of hearing issues. Some videos are simply too quiet and this saves my life. Makes content way more enjoyable.

A great option for people like me who don't hear well to amp up the volume
