On the newest version of Firefox after a full uninstall/reinstall - problem started last night. New install of Firefox didn't sync with my email, but after linking it on desktop via QR code, old passwords were reinstated. opened password manager again, and the problem where my phone accepts the pin or fingerprint, opens password menu for <2 seconds, then asks for pin or fingerprint again.

Menu is also slower than usual to load, causes the phone to hang on a black Firefox background colour screen when loading and only able to be forced to quit if I go back to the home screen, passwords menu comes back on screen if I don't force quit the app (back button goes back to blank passwords screen then asks for login again, android back button does the same.
