Sync is not a backup and recovery service so it may not keep or have that at times. It will also only save as per below.

2) https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles will Export your History as well but only : as per : Autocomplete history in formhistory.sqlite This file remembers what you have searched for in the Firefox search bar and what information you have entered into forms on websites. re: https://support.mozilla.org/en-US/kb/recovering-important-data-from-an-old-profile#w_autocomplete-history

Alternatively you can go to History then Show All History and click on a Month and right click and Copy to a Notepad then can save as a HTML File so they are clickable links.

I do not know if any History Managers are being developed or can be used due to security.

Please let us know if this solved your issue or if need further assistance.

Another way is to copy the folder of the profile you are using As Is to a thumb drive. Then plug the drive into the other system.

History is stored together with bookmarks in a database file named places.sqlite.

Windows doesn't include any applications to read .sqlite files, but you could download one from the web if you want to build your own queries.

A third party tool that can read Firefox history is: http://www.nirsoft.net/utils/mozilla_history_view.html. I think it has some kind of save or export feature, but I don't remember...

This is exactly what I was looking for. A way to read and organise the history data easily. Thank you.
