eCloud Favorites/Bookmarks not available

Summary

I can't find the Bookmarks Section in eCloud and Firefox (with Floccus) stopps syncing.

E033: Redirect detected. Please make sure the server supports the selected sync method and URL you entered is correct doesn't redirect to a different location. If the redirect is part of your setup, you can disable this check in the settings.

The problem

Steps to reproduce

1. LogIn into your eCloud Account
2. You can not find your Bookmarks
