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

Works great for what it is, but it seems to mess with some settings that prevents videos from playing on certain sites.
For example, it says on the console "Content-Type” of “image/gif” is not supported. But when I disable this add-on, it all works fine. There is a warning in the description, but it doesn't fit what my problem is.
Beware.

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

Extension work correctly! almost in any websites, love it👍

I M WATCHING MONEY HEIST IT'S GOOD TO WATCH ON HIGH VOLUME
