I'm listing this as a privacy setting because when I click the microphone button in WhatsApp web to enable audio input, there's a green popup telling me to select "Allow" in the box above, but that box above is flashing wildly and there's no way to click on anything. It appears and disappears about 10 times per second, and no matter how many times I try to click on "Allow" I can't catch it. It seems to progressively get slower as it ... what? runs out of breath? And the only remedy is to kill the WhatsApp window and start it up again, and to give up on using the microphone. Anyone else experience this or know what to do? I have confirmed that the mic is working, in other apps (Audacity), and it shows up in system settings properly. Thanks.

Why does Mozilla need to acess all files? Can we disable this 'feature'?
