Hi. My https websites are not accepted by Firefox on mob Android but drsktop version works fine. Also Crome works fine on bothe mob and desktop so i know my htaccrss 301 redirects are working fine. Mob Firefox returns the message "This site is untrusted" for urls https://www.pianclub.online and https://www.marycliff.co.uk Can you tell me what i can do to fix this please. Is my mob security level set too high in MacAffee perhaps? Best wishes Clifford
