the only sites I give permenant cookie exception are my selfhosted services
This is what I was referring to. How are you accomplishing this?
I’m still looking for the switches to block all new requests asking to access microphone, location, notification
I can’t help with this at the moment, but if you’re still struggling with this I can provide the lines required to disable these items. However, I don’t know how to do this with exceptions (ie allowing your self hosted sites to use that functionality, but block all other sites). At minimum though you could require Firefox to ask you every time a site wants to use something. This may get repetitive for things like your self hosted sites if you have everything clearing when you exit Firefox.
