On Firefox for Ubuntu version 56 on Ubuntu 17.10 Gnome X.Org I observed since the upgrade of FVD SpeedDial several problems with the syncing of the bookmarks. I can't access the syncing options for the bookmarks at initialization (Download, Marge, Upload) they are not displayed. By enabling the automatic sync option for the bookmarks duplicates are generated. I have the same exact problem on both my laptop and desktop.
