Restoring login information to desktop

I have Firefox Dev from the Aurora channel and regular Firefox installed in a Kubuntu linux box. They both have their own profile folders and are all synced, including the Android version. All was working fine.. I recently did an update of the Dev version, I think that's what did it, and after that I lost only the saved logins for it. I tried to sync from the regular desktop version and that wiped it's logins as well. Now I ONLY have the logins working on the Android Firefox. I don't want to mess with it and loos any chance of getting them back. Any thoughts on backing them up? From the Phone... How would I go about restoring them to my desktop versions? Thanks
