wilts43, your bookmarks and passwords etc. are stored locally in a folder on your harddrive. It is possible to copy this folder to a new machine, and then use it in the new Firefox without using Sync, if that is your preference.

Before attempting anything I would reccomend keeping a second copy of the original profile folder somewhere safe, as a backup.

One way to transfer your data could be to copy the original profile folder to a stick, and then copy its contents from the stick into the default profile folder of the new Firefox, while Firefox is not running (and assuming that you have not added any data to the default profile on the new machine, as this could be overwritten).

For detailed steps, see this link for both how to backup the profile on the original machine, and also how to import the data from it into the new Firefox. https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

You can copy certain files with Firefox closed from one profile folder to another profile folder to transfer your personal data. Note that best is to avoid restoring a full profile folder and only restore important files that are safe to restore/transfer.
