Just works and is FOSS! What is not to love?

This is the only tab volume extension that worked for me. All the others fell victim to the "The HTMLMediaElement passed to createMediaElementSource has a cross-origin resource, the node will output silence" error, but not this one

The only one I tried that actually works.

Constant issues with audio not working at ALL with this extension installed. Doesn't matter what percent it is, or how many updates the developer pushes out. If you use this addon and experience muted audio, disabling it is your only option.

While it does do what it promises, there are many sites that it breaks videos entirely

Actually works unlike other similar programs just make sure you restart your browser

This works so much better than the ones I tried that had more downloads. Truly a hidden gem

One of the best extensions. Them pesky sites that always reset volume than just lock it to a lower volume for that domain. The volume boost also works great on all sites without a delay.

it works perfect and mono and sterio changing is very good detail. i was using another extension for this. Thanks.

really successful thanks

it's awesome, thanks man

Works on Loom where I need it to boost volume, but makes videos on Pinterest have no sound. So, as a workaround, enable, disable, as needed.
