This article applies to Firefox, Thunderbird, Mozilla Suite and SeaMonkey.

  • "Security Error: Domain Name Mismatch" occurs if you make a secure connection to a server whose domain does not match the domain name in the certificate it uses. This is to inform you that the site you are trying to connect to may not be the site you wanted; however, this most frequently occurs when a site changes their domain name but doesn't buy a certificate for the new domain.
  • "Security Error: Server certificate expired" occurs if the site's certificate has expired.

In both cases, if you trust the server, you can can get rid of the alert by installing the Remember Mismatched Domains extension. It adds a "Don’t warn me again about this certificate for this domain" checkbox to the Domain Name Mismatch and Expired Certificate warning windows.
