Do I need to install any certificates in my browser to access web sites that use SSL or EV certificates issued by the InCommon Certificate Service?
No, you do not need to install any certificates in the browser. The AddTrust root CA certificate, which is required for browser access, ships with all known browsers. In general, intermediate CA certificates are passed from the server to the browser as needed, so yes, there is a certificate bundle that needs to be installed on the server, but not in the browser. If you are a site administrator testing a new server configuration, there is one caveat, however. Some browsers (such as Firefox) will store intermediate CA certificates received from a server in the browser’s certificate store, so unless you’re careful, you may be tricked into believing your server is configured correctly when in fact it’s not. Be sure to remove intermediate CA certificates from your browser’s certificate store before testing your server configuration.
