I am looking for a firefox extension that will allow me to toggle microphone access, preferrably per tab, for example disabling it while I’m not speaking in a zoom meeting to reduce tracking.
Edit: clarification due to misunderstanding: i want something that lets me toggle actually giving a site mic input without removing permissions
Probably not that useful for OP, as they want an extension, but: On Linux one could use pavucontrol to individually set volume (in and out) and devices for every single stream, including single tabs.
