Simple and Effective addon. does what it says, no intrusions. Perfect. Sound quality also remains consistent at higher volumes. Highly recommend it. More than satisfied. :)

Love it, works beautifully.

Works well for simple things like youtube but doesnt work on online meetings which is a bit annoying. I keep trying to make google meet quieter or louder but to no avail.

Nice and simple interface, works really well!

Simple and easy to use when in fullscreen mode: Win 10 was lacking with this.

Effectively work without distorting sound. I have watch some youtube videos which has very low sound. This extension solved the problem.

This add-on fixes the problem of low video volume introduced recently. It's essential if you watch videos online in firefox. The locate-tab-playing-sound function is nice also. Thanks Aliaksandr!

Does not work for controlling volume for each website. Useless

From the hard of hearing community, thank you sir

Good for raising volume or lowering volume for a specific tab. Great for making Youtube Music quieter.
Can adjust volume in 10% increments, from 0% to 600%. But does not save volume for if page is reloaded or closed. Adjusts volume for just one tab, not the whole website.

nice one

good
