Can use apple ID password on Safari and Apple Support but not from firefox,
I can sign in to iCloud from Safari and Apple Support from Firefox but not into iCloud from Firefox with Apple ID nor into Apple TV via Google on new Sony Smart TV. Am repeatedly asked to create new Apple ID password. Why does password work in some places and not others? Thanks, BTW, current password has six numerals, five letters and one upper case letter. Shouldn't that meet criteria?
