You have another support thread over here - https://support.mozilla.org/en-US/questions/1130631 - that sound very related to this question or an extension of that support thread. ---------------------- What information are you NOT telling us? The term "contacts" usually relates to '''email''' - Firefox doesn't do email, although Firefox will connect to a webmail website and will display and allow the Firefox user to interact with their "emails". '''But''' those "contacts" aren't stored in Firefox, they are held in the the email user account on the server that hosts that webmail service. Then - how do you get Firefox on a PC to have access to anything on an iPhone? Unless you are using the '''Firefox for iOS''' app on your iPhone '''AND''' have both that Firefox for iOS and the PC using the same Sync account. '''But''' even then, how would data that Firefox doesn't even save get synchronized? ''Or an I having a "senior moment" and missing something that is painfully obvious?'' Doesn't seem even remotely related to Firefox support to me.
