Hi @Ismarrero, firts ceck for an update in the App Store. If there is no update pending, have you created a Firefox-account with your actual installation? If yes, are you logged-in to this account on your device and have you enabled the synchronization? If also "yes", download Firefox on another device, desktop or mobile, log in to your account, start a synchronization. When sync is complete, delete Firefox on iOS followed by a fresh installation. Log in to your account and enable the synchronization to get your settings and bookmarks syced to your device.
