how do i stop firefox blocking google.co.uk

hi, first please make sure that the date, time & timezone are set correctly on your system. if this doesn't solve the issue (or it is already set properly), a possible solution depends on different factors: * what is the '''error code''' shown under ''technical details'' on the error page? in case the error code equals ''sec_error_unknown_issuer'', please attempt to inspect the failing certificate to see who is its issuer: enter ''chrome://pippki/content/exceptionDialog.xul'' into the location bar, and in the page that opens, set the server location to "https://www.google.co.uk" in order to retrieve and view the certificate like in the attached screenshot. * which '''issuer information''' does the certificate contain? please report back with those two pieces of information. thank you!
