Hello, I am sorry to hear that the Favorites from IE did not import properly. If this was done in the first install there is another work around to import:

First check to make sure they are not just hiding, after an import the favorites should be in the Bookmarks Menu directory.

You can check for problems with the places.sqlite database file in the Firefox profile folder.
