At your Mozilla FF browser you got a tab 'Bookmarks'. Click on bookmarks => manage bookmarks. At the first tab (don't know how it's called in English, but in Dutch it's called 'bestand') in the screen that will pop up you'll find an item 'export'. Firefox creates a HTM file that you can import in any other browser.
Also there is a little
program, wich syncs your favorits of IE with your bookmarks in FF.
