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.

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.
