Summary This story is about an issue I reported in July of 2019 via Bugzilla. The ticket is public from the 16th of January 2020, so I don’t disclose any new vulnerability. However, I think such posts are necessary to show the community how applications installed on Macs may harm their privacy. This post will show you how an attacker that achieves code execution on your machine may use Firefox to abuse your Privacy preferences (TCC) and thus access your microphone/camera/location and record your screen.
