fwiw: - i dont have an arm64 so i've never tested firefox there - if i had an arm64, i'm not sure i'll had time to actually test it there - and even if so, i wouldnt have the arm64 specific knowledge to actually help besides that, ktrace and egdb are the tools... you should be able to install the debug symbol package, and examine coredumps.
