Hi denueve, It can take a while for your phone to realize that your Firefox Account is verified. It needs to do a sync to get caught up. On some devices, that can take a while. (In the future, we're going to not bug the user with the unverified notification for a while, say a day or two.) You can force a sync from Android Settings > Accounts ... > [your account] > Force sync, or browsing a few sites in Fennec should trigger a sync. Hope that helps, and please respond if your phone keeps complaining!
