Certificate warnings

Firefox uses certificates on secure websites to ensure that your information is being sent to the intended recipient and can't be read by eavesdroppers.

Certificate will not be valid until (date)

(site name) uses an invalid security certificate. The certificate is not trusted because the issuer certificate has expired. The certificate will not be valid until (date). (Error code: sec_error_expired_issuer_certificate)

This error can occur if your computer clock has the wrong date, in which case the date given in the error message will be in the past. To fix the problem, set your system clock to today's date and time (double-click the clock icon on the Windows Taskbar).

The certificate expired on (date)

(site name) uses an invalid security certificate. The certificate expired on (date). (Error code: sec_error_expired_certificate)

This error occurs when a website's identity certification has expired.

This error can also occur if your computer clock has the wrong date. To fix the problem, set your system clock to today's date and time (double-click the clock icon on the Windows Taskbar).

Certificate is only valid for (site name)

(site name) uses an invalid security certificate. The certificate is only valid for (site name). (Error code: ssl_error_bad_cert_domain)

This error is telling you that the certificate sent to you by the site is actually for another site. While anything you send would be safe from eavesdroppers, the recipient may not be who you think it is.

A common situation is when the certificate is actually for a different part of the same site. For example, you may have visited https://example.com, but the certificate is for https://www.example.com. In this case, if you access https://www.example.com directly, you should not receive the warning.

The certificate is not trusted because the issuer certificate is unknown

(site name) uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown. (Error code: sec_error_unknown_issuer)

The file cert8.db in your profile folder may have become corrupted. Delete this file while Firefox is closed.
