Certificates are a component of encryption used in Internet communication. They ensure that the party on the other end of your encrypted connection is who they say they are. For a more thorough explanation of certificates, see Wikipedia's articles on TLS and X.509.

Untrusted connection or certificate

When using some sites and services at Gevirtz, you may come across the occasional "untrusted" connection or certificate. This is the case with services such as WebRE and Daphne. The reason for this is that it is uneconomical to purchase a certificate from a vendor for every service that we operate, so only our most front-facing services use commercial certificates. For other services, we create our own. The encryption is just as strong and just as safe, but your browser will (rightfully) warn you that something seems fishy because this certificate is not signed by a certificate authority (CA) such as Verisign. In these situations, you must add an exception to your browser so that it will trust our certificate and connect to the server.

Adding an exception in Firefox

When you try to visit a website using an untrusted certificate in Firefox, you will be presented with a warning.

If the URL does match the website you're trying to access, click I Understand the Risks, then click Add Exception....

Firefox connection is untrusted i understand the risks add exception.png

Next, check again that the URL is for the site you mean to visit. If it is, then click Confirm Security Exception.

Firefox add security exception confirm security exception.png

That's it! You're all done. You may get this warning again if we update our certificate.
