Firefox 8 not displaying addons, error code:sec_error_unknown_issuer
I receive the following error message when opening the addons tool bar...
support.mozilla.com uses an invalid security certificate.
The certificate is not trusted because the issuer certificate is unknown.
(Error code: sec_error_unknown_issuer)

Check the date and time in the clock on your computer: (double) click the clock icon on the Windows Taskbar.
Thanks for the reply, but I checked and my date and time system settings are correct. Is there another reason why this would be happening. I have uninstalled/reinstalled firefox a number of times with no success.
Did you check the details of that certificate like the issuer and when it is valid by retrieving the certificate?
- Click the link at the bottom of the error page: "I Understand the Risks"
Let Firefox retrieve the certificate: "Add Exception" -> "Get Certificate".
- Click the "View..." button and inspect the certificate and check who is the issuer.
You can see more Details like intermediate certificates that are used in the Details pane.
