There is a serious fault with Firefox and synchronising ,my phone email is full of blank links sent that should have links to download,the data is floating about somewhere as my Laptop tells me so !!!. My email is fully working on the phone as I downloaded My BT. The QR did work after lots of mishaps . To make matters worse Google refused Firefox browser so I took it off and downloaded again, they said it was not secure ?.Quite frankly I am pretty hopeless with these gadgets and would like a very simple solution to my dilemma, any suggestions would be gratefully received.
