I want to restore my information on a computer that was recently reformatted

I recently had to have my computer reformatted due to a virus and want to restore firefox as it was before. I have mozilla backup, but the profile stored there is out of date. But I had been using firefox sync before the reformat, so theoretically the updated info is available. I just need to know how to access firefox sync on my newly reformatted computer and sync up firefox with sync.

Did you print or save your Firefox Sync key? I think you will need that to retrieve your data.

Note: if you change your Sync key, that may wipe out your stored data.

I did save the sync key - and I solved my problem. I was thrown off by the fact that FF first seemed to want me to put in information from another machine. That "other machine" had, however, effectively been destroyed and I was just trying to put FF back on the recently-wiped computer. Fortunately, the Sync set-up had a link for people who could not access the other machine (I wish it had been clearer the first time). When I clicked on that, I was able to put in my sync account information and the sync key; when I restarted FF, there was all my information. It was like I had never had to reformat the computer.

I wish, however, that this had been explained in a more clear and logical manner. Considering that so many people have had this problem, it might be a good thing for the Powers That Be to look into
