I installed Firefox on a new computer and tried to log into my sync account to migrate the data over. When I put in my email it keeps telling me that the account doesn't exist. I verified the email address on the old computer and it's correct. I even tried to reset password but when I put in the email address again it said it didn't exist. I created a new account with the same email address with no problems. I just can't figure out how to migrate all my data from my old computer. Thanks in advance for your help.
