Every time I start Firefox, I get the following error message from Sync:

"Sync encountered an error while connecting:Incorrect account name or password. Please try again. [Preferences]"


In my about:log-sync, these lines appear: 

Sync.Service	DEBUG	Exception: Login failed: error.login.reason.account No traceback available
Sync.Service	DEBUG	Not syncing: login returned false.

Turns out that my Sync password was not correctly saved in Firefox. When I looked at my password saved in my Firefox profile (Options -> Security -> Saved passwords -> Show passwords) , some characters were different than the one I entered when I set up my account. For instance, there was an "©" instead of a "(".

I solved by it changing my password and using only "a-z" "A-Z" "0-9" characters.
