Mozilla forums have so much more buzz words and technical stuff, much more than the above, but it mentions CSs many times and looking it up in Wiki gives the following;
In cryptography, a certificate authority or certification authority (CA) is an entity that issues digital certificates. A digital certificate certifies the ownership of a public key by the named subject of the certificate. This allows others (relying parties) to rely upon signatures or on assertions made by the private key that corresponds to the certified public key. In this model of trust relationships, a
CA is a trusted third party—trusted both by the subject (owner) of the certificate and by the party relying upon the certificate. Many[quantify] public-key infrastructure (PKI) schemes feature CAs.

So since certificate authorities tell the firewall what sites to let through, or not, this web site has figured out a way to get past your computer's security.
