The error is "Unknown account: Sign up". I can log in just fine with the same account on https://account.services.mozilla.com/ though.

Particular to my setup: 

* My email address contains a "+". 
* I didn't remember my password, so I changed it to a new one in the Preferences on my first device (but, as I said, the new one works fine on https://account.services.mozilla.com/)

hello, firefox 29 and upwards is using a different sync system which isn't compatible with accounts set-up in older versions. you'd have to create a new account to migrate to the new system (you can use the same mail there): Sync your Firefox bookmarks, history, passwords and more
