Problem with Sync
I am running Firefox on my Windows 10 desktop, where I have many bookmarks. I am now also using Firefox on a laptop running Linux (Kubuntu) and would like to sync it with the desktop, so that all my bookmarks are available on the Linux laptop. I have set up Sync settings, and clicked on Sync Now; then when I hover mouse on the Sync Now button it says "Last sync: 5 seconds ago". But nothing changes on the laptop -- no added bookmarks. I must be missing something, can you help? Many thanks.
