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.

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.
