I learned about this extension from an Asmongold video—he uses it to adjust the volume of online videos and enable mono audio output. That's why I recommend giving this extension

makes videos on x mute.

On sites where it works the extension is very helpful. However there are several sites where I have had to disable this extension to play video at all, including Hulu and Peacock.

I get some videos in other tabs without audio.

Mutes audio on some sites I wanted to use it on. Works perfectly on sites where I don't need it. Great.

does everything it promises and more

Warning, this prevents my Amazon Prime videos from playing at all. Maybe caused by some lack of DRM code.

Good, but it's just a compressor... I need something that boosts the volume with any compression being applied.

In some websites I don't have any audio - where I used to - until I disable this extension.

Horrible. Half the sites I go to brick the player until I turn off the volume booster. So dumb

working great on zen browser

Awesome cool feature.

mutes all audio when active

Does the job amazingly!
