Are you sure that the date is also OK (you wrote about the time)?


You can rename the file cert8.db to cert8.db.old in the Firefox Profile Folder to remove all intermediate certificates that Firefox has stored by visiting secure websites.
If that helped to solve the problem then you can remove the renamed file cert8.db.old unless you have user certificates that you may want to export first and import them in the new file.
Otherwise you can restore the certificates by renaming (copying) the file back to cert8.db

The certificate is valid from 07/09/2011 until 07/13/2012

Check the date and time in the clock on your computer.

The time is right. Now what?

Do you have the certificate with the dates that I posted above?

What dates do you see if you retrieve the certificate?

If not then you may have an older, expired, certificate stored that you need to remove.
Always be cautius with creating a permanent exception to certificates.

The certificate is up to date, this is why I was confused. Here is the screen shot.
