does not work

There is an issue. Installed it and tried adjusting volume. Started audio and it was silent. Turned it up, turned it down— still silence. Restarted Firefox, played audio. Audio worked. The moment I click the add-on icon, audio cuts out.

Install this to disable Firefox sound altogether. Very useful.

Doesn't work, crappy UI too.

Doesn't work

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

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