We are getting the following error message The certificate is not trusted because the issuer certificate is unknown. The server might not be sending the appropriate intermediate certificates. An additional root certificate may need to be imported. Error code: MOZILLA_PKIX_ERROR_MITM_DETECTED

We are not using any AVAST, but we are using mcafee. Import root certificate to, but it is still failing and unable to find the company root certificate.

What is the value of this pref on the about:config page?

  • security.pki.mitm_canary_issuer

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.
