I use FFox on Windows 10 and Android, version 89.0.1 64 bit. It is not my default browser. When I open FFox sometimes I am connected to my account and can synchronise and sometimes not. I therefore have to sign into account using email + password which I have to look up. Please provide clear settings for W10 + Android so that I always sign in and can sync. Using the QR code on my monitor NEVER works . Regards T J Green
