(d) You have exceeded the session time out. This Connection is Untrusted You have asked Firefox to connect securely to accounts.google.com, but we can't confirm that your connection is secure. Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified. What Should I Do? If you usually connect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue. The server's security certificate is not yet valid! You attempted to reach www.google.com, but the server presented a certificate that is not yet valid. No information is available to indicate whether that certificate can be trusted. Google Chrome cannot reliably guarantee that you are communicating with www.google.com and not an attacker. You should ensure that your clock and time zone are set correctly on your computer. If they are not, you should correct any issues and refresh this page. You cannot proceed because the website operator has requested heightened security for this domain. accounts.google.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate has expired. The certificate will not be valid until 7/21/2011 5:30 AM. The current time is 1/1/2004 12:43 AM. (Error code: sec_error_expired_issuer_certificate) Help me understand When you connect to a secure website, the server hosting that site presents your browser with something called a "certificate" to verify its identity. This certificate contains identity information, such as the address of the website, which is verified by a third party trusted by your computer. By checking that the address in the certificate matches the address of the website, it is possible to verify that you are securely communicating with the website that you intended and not a third party (such as an attacker on your network). Certificates have a validity period, much like any identity document (such as a passport) that you may have. The certificate presented to your browser is not yet valid. When a certificate is outside of its validity period, certain information about the status of the certificate (whether it has been revoked and should no longer be trusted) is not required to be maintained. As such, it is not possible to verify that this certificate is trustworthy. You should not proceed.
