I've got all my bookmarks arranged on Firefox desktop into various folders and there are also various bookmarks in the Unsorted Bookmarks folder that are sorted by date added. I've connected to Firefox sync and synced the desktop. I've then installed firefox mobile on android and connected that to Firefox Sync. This then syncs all my desktop bookmarks on to Firefox mobile. However when I go back into Firefox desktop the order of my unsorted bookmarks has been changed and ordered by name.

I assumed that either Firefox Desktop would be the master and everyother device synced with this would follow the same order or that the first device linked (the desktop) would be the master. However Firefox mobile seems to sync the bookmarks, change the order and then sync this new order with the desktop.
