Where does the box appear? Does it block you from using Firefox? If there is a mostly blank box centered over the display with a gray bar, checkbox and a question mark, that may be the AOL Toolbar issue. Updating AOL might resolve that issue, or you could remove/disable the toolbar. If there is a different box, perhaps it is some kind of partially blocked advertising. Could you post a screenshot of how the box appears?
