Secure Connection Failed

The certificate expired on 01/12/2010 02:31 AM.

(Error code: sec_error_expired_certificate)








* This could be a problem with the server's configuration, or it could be someone trying to impersonate the server.

* If you have connected to this server successfully in the past, the error may be temporary, and you can try again later.







Or you can add an exception…

You can just choose to add an exception and you'll be able to continue.

Hit the add an exception link it gives you... I do not know why firefox does this in such an ugly manor when other browsers handle it better. I think older versions of firefox also handled this better then newer ones so more then a bit strange.

You might also want to check the date that is set on your computer. Since the certificate in your original post doesn't expire until next year, you likely have a date issue.
