Q: I am receiving a 12192 error in Firefox and cannot access sites that need my personal certificate. How can I stop this error?
Version 2.x Firefox browser gives this error message when your have multiple personal certificates installed.
To remove a personal certificate:
- Go to the Firefox > Preferences.
- Select Advanced, click on the Security tab, then click View Certificates.
Here you should see all the certificates that are installed.
- If you have multiple copies of your personal certificates, delete extra copies and leave only one.
It is also possible that your personal certificate is corrupted in which case you will need to remove the existing certificate and request a new one from the Certificate Page: https://ca.mit.edu/ca/
