I just replaced my Win 10 desktop with a new Win 11 desktop. I downloaded Firefox OK, but my bookmarks are no longer there, of course. I was told that there was some way to recover them to this machine, but I didn't get any details how. In fact, the person implied they would just appear when I downloaded Firefox to the new machine. Of course, this didn't happen. Firefox did appear to recognize me (got a "welcome back, by the way" message near the top of the page). Can I somehow recover my old bookmarks to this machine?
