Why can't I sync my passwords?
This article is no longer maintained, so its content might be out of date.
If the Passwords checkbox is disabled in the Sync preferences window, it's because you have set a master password.
Firefox Sync will not synchronize your passwords if a master password is set. If you would like to continue synchronizing your passwords, try removing your master password before synchronizing.
This issue will be resolved in Firefox 34.
