I have two email accounts I've used for Firefox over the years, a Google account on my PC and a Yahoo account for my mobile phones. I don't see a secondary email account on any devices when managing my account, yet when I get go to add them, all devices say they already exist. I am doing this because I am trying to sync one phone to another. Or, by pairing one to a window on my PC and then pair the second phone to that after that's accomplished. I didn't see a Sync and Save opinion in my phone menus, and under my email address there is only an option to sync now and no pairing options, nor a QR reader that comes up to see the QR code on my PC trying to sync from there. I cannot even get my new phone to log in to Mozilla to even ask this question. My PC account options shows that both phones exist in the sync system.
