You can check if there is more detail available about the issuer of the certificate.

  • Click the "Advanced" button show more detail
  • Click the blue error text (SEC_ERROR_UNKNOWN_ISSUER) to show the certificate chain
  • Click "Copy text to clipboard" and paste the base64 certificate chain text in a reply

If clicking the blue error text doesn't provide the certificate chain then try these steps to inspect the certificate.

  • Open the Servers 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 its 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.
