How can I eliminate the SEC_ERROR_UNKNOWN_ISSUER errors I get at multiple websites?

I just installed FF 63 on a 64-bit Windows 7 machine, and I'm getting SEC_ERROR_UNKNOWN_ISSUER errors at many, but not all, websites. Reaching the same websites via the same URLs using Chrome works fine.

All discussions of this problem seem to lead to https://support.mozilla.org/en-US/kb/error-codes-secure-websites?redirectlocale=en-US&redirectslug=troubleshoot-SEC_ERROR_UNKNOWN_ISSUER, but it's not helpful. My antivirus is Bitdefender Free, which appears to have no option for disabling the interception of secure connections.

Running FF in safe mode behaves the same as in "normal" mode: I get SEC_ERROR_UNKNOWN_ISSUER errors at many (but not all) websites.

Help? As things stand now, FF is pretty close to useless for me.

I reinstalled my OS. since firefox is not saving my settings, it keeps going back to default. my extensions are not working. I have uninstalled and reinstalled many times. it's not saving my credentials even though I have set it to save cookies till they expire.

Suddenly, most sites have invalid signature. That includes sites that I visit on a regular basis. Firefox is unusable-I can't visit most sites

secure connection failed- all of a sudden, this is most sites, including sites I visit daily
