I have installed Firefox (version 90.0.2) on macOS version 11.5.1. In the Camera and Microphone panes under the Privacy tab in Security & Privacy settings, Firefox is missing.
Yet, when I approved it on Firefox, the Mac privacy dialog did not pop.
How can I give permissions to Firefox for microphone and camera to be able to use them in Firefox? (should it be by modifying the privacy database?)
