I am unable to go any search engine site or use any search engine, including yahoo, bing and google. I keep getting a message saying "Your connection is not secure". When I click advanced it says whatever site "uses an invalid certificate" and I am unable to add it as an exception. The error code is SEC_ERROR_UNKNOWN_ISSUER.
