I've bought a new Win10 PC to (eventually) replace my old one.

I've signed up for a Mozilla account on the old PC, signed into it from the new PC and the favourites, history etc have come across ok onto the new one. The saved logons however haven't.

How can I get my saved logons to sync across from the old PC to the new one?

You can open about:sync-log via the location bar to see whether recent Sync logs are available. You can upload the file to a website like Pastebin if you can't post the content of the file in a reply.


You can export the logins in Lockwise to a CSV file and import this file on the new copmuter.

See the note at the bottom of this article about how to enable CSV in Lockwise import via the about:config page.
