OSX 10.14 adds persisted-to-disk permission prompts for WebCam/Mic access
OSX 10.14 Beta has added OS-level permission prompts for Mic/Camera access. According to Mozilla's prelimimary testing the behavior was:
The description I found said the OS should cache the results of the prompt. Did a quick test - 1st try: get the the Firefox dialog then two OS dialogs for the "Firefox" process (camera and mic), 2nd try: get OS dialog for "plugin-container", 3rd try: no OS dialogs
I requested we file a bug about persisting this to disk in Private Browsing mode (and what, if anything we could do about that...) but I wanted to get this bug on file for Tor Browser.
It seems like a user who uses Tor Browser and uses the mic or camera will create a disk persistence that they had done so, with timestamp.
