Weird. This is what I get:
Websites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for tools.usps.com. The certificate is only valid for the following names: www.costco.ca <http://www.costco.ca>, costco.ca
Error code: SSL_ERROR_BAD_CERT_DOMAIN
https://tools.usps.com/go/TrackConfirmAction_input?origTrackNum=1234567890
Unable to communicate securely with peer: requested domain name does not match the server’s certificate.
