As I find something in ebay I attempt to sign in to watch it or purchase it. Never had this problem until the last 2 weeks or so. The Firefox alert comes up not to trust the site. It says: signin.ebay.comuses an invalid security certificate. The certificate will not be valid until 1/18/2011 6:00 PM (Error code: sec_error_expired_certificate) Please help me as I watch and use ebay daily.
