hi, can you use another browser on the affected system, visit google.com and inspect who is the issuer of the certificate (https://apple.stackexchange.com/questions/152469/view-tls-certificate-in-safari-8-yosemite)? should probably be Google Trust Services if the secure connection isn't intercepted/tampered with...

You can try these steps to inspect the certificate.

  • open the Server tab in the Certificate Manager
    • Options/Preferences -> Privacy & Security -> Certificates: View Certificates -> Servers: "Add Exception"
  • paste the URL of the website (https://xxx.xxx) in it's location field.

Let Firefox retrieve the certificate -> "Get Certificate"

  • click the "View" button and inspect the certificate

You can see detail like the issuer of the certificate and intermediate certificates in the Details tab.

Same issue here but on Nightly build.

So far errors is just: SSL_ERROR_BAD_CERT_DOMAIN and SEC_ERROR_UNKNOWN_ISSUER
