hi. can anybody explain me the message SEC_ERROR_UNKNOWN_ISSUER when i use connection inside my company

when i add site to exclusion does firefox continue to protect my connection to site by using TLS or firefox stop use TLS and passwords transmit openly?

it is important to understand to me have i install a valid certificate on all my equipment to protect my connection inside the company.

or just add site to exclusion , because i know that certificate have been generated randomly and my connection and passwords to equipment is still by protection TLS.

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.
