In order for a browser to accept a certificate, it must be able to link it to a 'trusted root certificate'. Trusted root certificates are embedded into popular browsers such as Internet Explorer, Firefox, Chrome and Comodo Dragon. These root certificates are used as trust 'anchors' to verify the legitimacy of all website certificates that the browser encounters. If a browser encounters a https://www.instantssl.com/ssl-faqs/ssl-certificate-errors.html certificate that is not signed by one of these roots, then it will state it is untrusted and visitors will see an error message like the one above. Most trusted root certificates in a browser are owned by an accredited Certificate Authority (CA). When a CA signs the certificate of a website, it is effectively 'linking' that website's certificate to one of their trusted roots in the browser certificate store. For security reasons, most CA's do not sign end-entity/website certificates directly from the root, but will instead use an 'intermediate certificate' to create a 'chain of trust' to the root. In this system, the root certificate will sign the intermediate and the intermediate is used to sign the certificates of individual websites.
