I have never used Firefox Sync so i gave it a try. Then found out it is indeed very useful until i got an error: Error While Syncing. I fixed by changing my password. But the error came back and i ignored.
I searched and found out that one solution was to reset and do it again so i deleted my sync data and then deleted my account.
Now i cant do nothing !!! I even created a new account but the button "I have an account" doesn't work.
I can't see the code, the one to pair a device. I can create a new account but it won't log in.
I tried to recover my Sync account with the Recover lost password but all i get is a message saying "We were unable to log you in"
I'm thinking in reinstall firefox with my old profile data but one file might be corrupted and then i will be unable to fix the problem.
