Basically a databse application has this button that allows users to view as PDF instead of printing etc, so when they click this button IE launches to display\handle the PDF and this is when the crash happens as well. The database application explicity tells IE to open it, so theres no way to just direct FireFox to open it even if FireFox actually worked. So I really need IE to at least open for the user, not necisarilly have WAN access or anything like that, its just used to view the pdf.
