I repeatedly receive" Your connection is not secure" with the Advanced detail" SEC_ERROR_UNKNOWN_ISSUER" on my desktop Firefox but my laptop still can access the problem sites on Firefox. Both are using WIN 10 and can access the websites using Google Chrome or IE11. Any suggestions? Many Thanks Stephen
