Is Firefox obsessed with security? Rules for SSL_ERROR_BAD_CERT_DOMAIN error are too rigid

Posted

When I open a site, I receive a "SSL_ERROR_BAD_CERT_DOMAIN" error. This is because the site recently changed their domain.

However, there is no option to add an exception after clicking "Advanced" and go to the site. Edge browser allows me to still visit the page, but doesn't recommend it. And Firefox just blocks the site.

There should always be an option for a user to visit any site regardless of security errors.

Hi, Good one. For a nice round number Firefox 60 released today : uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files , C:\Program Files(x86) & C:\ProgramData Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do :

Reinstall with Current Release Firefox 59.0.3 with a Full Version Installer

Please let us know if this solved your issue or if need further assistance.

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 SEC_ERROR_UNKNOWN_ISSUER message to show the certificate chain
  • click "Copy text to clipboard" and paste the base64 certificate chain text in a reply

If clicking the SEC_ERROR_UNKNOWN_ISSUER text doesn't provide the certificate chain then 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.
