If you can't associate the tab volume with tabs, then FTFO... don't need another useless icon overlowing my Firefox bar

I have tested this extension on Dailymotion. The volume has not changed. This extension is absolutely unusable.

Doesn't work. Doesn't do anything.

No effect. Volume doesn't change

Does not work/ no effect

Tested with bandcamp only. When adjusting volume, it not only has no effect, but playback stops, and i can only resume by reloading the site. Similar to "600% Sound Volume" plugin.

Doesn't save my setting for volume, totally useless.

Does absolutely nothing.

Doesn't work. Tested on Google Meet.
