So, here, for my own use and yours too if you have the need, is a very simple program to export bookmarks from Chrome to a standard document (the age-old bookmark.html file) usable by Firefox or IE (or I would imagine just about anything else).
While I was there, I also added the tremendously useless button to remove all download history as well - another item that seems to not be available yet in Chrome itself.
