Hi Dave, one option is to use Sync, but not all categories of data will sync. You could try it and see how successful it is. For more information, see: * [[Back up and transfer your Firefox data to a new device]] * [[How do I set up Sync on my computer?]] Another option is to move files between disks. You will need to set Windows to show hidden files and folder: https://support.microsoft.com/en-us/windows/view-hidden-files-and-folders-in-windows-97fbc472-c603-9d90-91d0-1166d1d9f4b5 Then see: * [[Back up and restore information in Firefox profiles]] * [[Recover important data from an old profile]]
