I am logging in on my Apple laptop (by means of password protector) and using a FIDO device for authentication.  I usually get a failure message before I have even activated the FIDO device; then if I try again the whole browser freezes - no windows will work (yet when checking "force quit" it doesn't show it not responding.)

I have for years used Firefox for logging into BofA. I have not changed my configuration but 4 or 5 months ago I started having problems. My browser is always up to date and I have standard privacy settings. In the past the problem was that the authentication wouldn't work, then firefox would freeze I would have to close the browser - when I restarted I would still be logged in (which seems strange). Now most recently when I log it it doesn't accept my credentials. I have tried removing BofA from enhanced protections and clearning the cookies related to BofA - but the problem persists.
