SEC_ERROR_UNKNOWN_ISSUER on school district website
When attempting to access https://www.muasd.org which is a school district website I get the warning message with the reason stated above as SEC_ERROR_UNKNOWN_ISSUER. This happens on version 79 also on the enterprise quantum version as well as android firefox app. We took a brand new computer out of the box installed firefox while connected to a phone hotspot and received the same error. All other browsers work fine. Any help would be appreciated.

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