Firefox always immediately crashes on startup, giving a message popup box saying: "We're Sorry Firefox had a problem and crashed. We'll try to restore your tabs and windows when it restarts. To help us diagnose and fix the problem, you can send us a crash report." It then crashes again if I select Restart Firefox, and crashes even if I quit and restart it later. I have uninstalled Mozilla multiple times with a clean removal and redownloaded and reinstalled and the same thing happens. Also persists even with numerous restarts between removal and reinstallation. Crash ID: bp-fc0e63cc-13b5-4657-995f-8dfa02150919 is one of these crashes. Firefox used to work all the time every day; this started 4 days ago--no new installs of anything else.
