For reasons known only to it, Mozilla decided that it needed sustenance. So it ate my bookmarks. Seriously. Every bookmark I had is now gone, gone, gone. I can reconstruct a lot of it from history or from memory (combined with Google), but there are things that I'm sure I bookmarked for future reference that are now gone, gone, gone. This, sadly, includes a few blogs that I had just started reading on a sporadic basis, at least a couple of which I was planning on linking. I don't know if I'll find all those again. Hopefully I will.
This is the first major "episode" I've had with Mozilla.
