Hi, you can try using Sync: [[How do I set up Sync on my computer?]] ------------------- Or, plug a USB flash drive into your old machine, then in Firefox, open bookmarks > Show All Bookmarks > Import and Backup > Export Bookmarks to HTML. ''Or'' > Backup, but note that Backup will overwrite any existing bookmarks. Now save to the flash drive. You can now plug the flash drive into your new machine, then in Firefox, open bookmarks > Show All Bookmarks > Import and Backup > Import Bookmarks from HTML. ''Or'' > Restore (from Backup), and navigate to the flash drive. More: [[Import Bookmarks and personal data from another browser]].
