I don't have account but I can get to their page without problem. I think it boils down to over active A/V or firewall. Otherwise if you have adblockers that could also be causing the connection issue.

Hi try : 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 59.0.1 with a Full Version Installer

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

Could you please provide more detail 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.
