does not work

Doesn't work, crappy UI too.

Doesn't work

It doesn't affect "apps" in tabs like games. Only videos, so not tabs.

didn't work on scratch.mit.edu

it worked perfectly for me.

Ohne Funktion. Man kann den Regler verschieben, der Tab plärrt weiter laut.

no permissions required, does what it says

Can't assign shortcut comparing to the "600%" one.

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.

A great tool to boost twitter space volume.

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.

This is great! Thank you for sharing :)

not working work in ig story

works perfectly, simple gui, easy to understand icon, looks somewhat like its part of vanilla firefox when pinned.

It works

Functional, but when trying to lower volume it doesn't allow volume to go below what it was set at. Tried Youtube Music, and Youtube.
