If you're no longer using your Mozilla account on a particular device (especially when you're giving access to your computer to someone else), you should sign out of your Mozilla account to help ensure that no one can access your synced bookmarks, passwords, add-ons and browsing history.
You can also delete your synced data from that device when you sign out.
