I'm running Firefox in 4 different machines and they are all in sync mode. The problem is, everytime I start Firefox on any of these machines, I receive an alert saying that my account name or password are incorrect and that Sync will try again automatically. Nothing happens, so i click the preferences button beside the message, update my password and Sync starts to work fine. How can I solve this? I've deleted my account 3 times and started new ones but I'm still having the same issue. Can anybody help me please?

  • What version of FF are you using? Latest? Googling for this issue turned up several ticket for it on various sites. google.com/… – slm Dec 29 '12 at 13:24
  • Version 17.0.1 and I've also looked for a solution in google but could not find any. I'm begining to think that maybe my Router's default Firewall is blocking something. – Flavio de Souza Dec 29 '12 at 19:15

I had the same problem with Firefox 20.0.1. I solved it when I saw that my Sync password saved in Firefox (Options -> Security -> Saved passwords -> Show passwords) was not the same as the one I entered when I set up Sync. Some special characters (like é) were replaced by other characters.

So I solved the issue by changing my password and using only a-z A-Z 0-9 characters.
