Hi! Have you set up the account in your desktop? Can you describe what do you see? I believe that you haven't set up your Sync account yet and what do you get in the Sync tab is a "Set up Sync account". Take a look to this article and let me know if it helps: [[How do I set up Firefox Sync?]] If this is not what is happening to you it would be great if you can share a screenshot or at least a description of what you get.
