My Sync account isn't recognized?
According to "https://account.services.mozilla.com/" I have an account and data stored with Firefox Sync. However, when I try to log into Sync from "about:accounts" with the same email it doesn't recognize the account.

It might be that you use that account which is not saved on server.Check once again if there is showing something like this Unknown account??
