Firefox Version 79.0 OS: MacOS Catalina 10.15.6 Crash ID: bp-2f217397-5062-4f92-8cff-5e5770200823 Symptom: After updating Catalina to 10.15.6, Firefox fails to launch, crashes launches crash reporter, then closes. Clicking restart results in same behavior. I also seem to be unable to launch Firefox with the --safe-mode flags. Please advise. Dump: AbortMessage: ###!!!
