My son's is running vista (home premium) and firefox 3.0.5. The open file & save file dialog boxes no longer appear. When File, Open file or save page or save image is clicked on, nothing happens. I can view source, get the organize bookmarks dialog, but nothing directly related to open/saving local files. I do get the save dialog box in IE. I've uninstalled FF, deleted the profile and deleted the program file directory, reinstalled with the same result. Any way to re-enable these abilities?
