ideato, thank you for your reply. perhaps I am missing it, but I cannot find anything in these articles about how to create bookmark folders on Firefox/Android, not how to move bookmarks between folders. I can see how to sync bookmarks to desktop, organize them into folders on desktop, and then sync the folders back to phone. I am hoping for something that can be done just on the phone.
