Try to rename the cert8.db file (cert8.db.old) and delete the cert_override.txt file in the Firefox profile folder to remove intermediate certificates and exceptions that Firefox has stored.
If that has helped to solve the problem then you can remove the renamed cert8.db.old file.
Firefox will automatically store intermediate certificates that servers send in the Certificate Manager for future use.
You can use this button to go to the current Firefox profile folder:
- Help -> Troubleshooting Information -> Profile Directory:
Windows: Show Folder; Linux: Open Directory; Mac: Show in Finder - http://kb.mozillazine.org/Profile_folder_-_Firefox
You can retrieve the certificate and check details like the issuer of the certificate and the certificate chain.
- click "Advanced" to expand the error message
- click "Add Exception" to open "Add Security Exception"
If this isn't possible then open the Certificate Manager and go to the Servers tab.
- Options/Preferences -> Advanced -> Certificates: View Certificates
-> Servers -> "Add Exception" button
- 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 details like the issuer of the certificate and used intermediate certificates in the Details tab.
