I'm reinstalling Windows on my computer after a hardware issue, and I do have a backup of my old data. I was using Firefox Sync, where this "device" was called "Firefox Maison". When I reinstall firefox on my new computer, how do I make it a continuation of the former "device"/session, rather than it being registered as a new device with the same "Firefox Maison" name ? I sent tabs from another device to "Firefox Maison" while the computer is kaput, and Ideally I would wish these tabs to appear on my new Firefox when the operation is finished - if this particular thing can't be done that's not the most important, but I think it helps understanding what kind of continuation I want to do. The restoration of my (normal) open tabs would be much more important, for example. I managed to do that when a very similar issue happened to me some months ago, but it was clanky with appdata files, and I feared corrupting my sync session in some way, and/or losing data, so if anyone has a more reliable walkthrough, that would be ideal.
