I can open google.co.nz and get to the homepage. When I try to do a search, I get an Untrusted Connection error. When I try to add an exception, I view the certificate and it comes from google. Firefox's error message then tells me the site has a valid, verified certificate and there is no need to add an exception. The "confirm exception" and "permanently store exception" options are grayed out so cannot be clicked. When I go back to google, I get the same Untrusted Connection error.
