I do not fully understand what you are trying to explain. Firefox certainly does not ordinarily update or change your IE favourites. (You are able to export Firefox bookmarks in a suitable {HTML} format though) Firefox bookmarks are not the same as IE's favourites. You are able to import the HTML favourites from IE. Firefox then converts these to the required Firefox formats and keeps the bookmarks to itself. Unless possibly you have some utility that exports the Firefox bookmarks and over writes the IE files ? Or maybe you are just reading HTML files and folders with Firefox instead of using Firefox bookmarks. Have a quick read of these articles and post bask with more information about what is happening.
