I'm still running FF v2 and I have only experienced one problem with it (some youtube videos flicker) in several years.
I have IE6 or IE7 on the PCs as well, and have had many more problems with them, although I suppose I've been using IE longer.
You can open FF bookmarks manager (organise bookmarks) and choose File / Export (as a HTML file). Then open IE and go to File / Import Export, import the file you just created.
You could also just point IE import to the location of the FF bookmarks file - C: \Documents and Settings\NAME\Application Data\Mozilla\Firefox\Profiles\abcdefg.default\bookmarks.html
