My Windows 2000 system seems to have messed up my Firefox settings somehow. When opening Firefox 1.5.0.1, as well as the previous version 1.5, there is a message at the bottom: <!DOCTYPE window SYSTEM "chrome://prefbar/locale/prefbarOverlay.dtd"> with a line of dashes below ending in a ^ just below the >. Other symptoms: the bookmarks toolbar doesn't show up, and the Help field is missing in the main toolbar. Suggestions? (I don't have a userchrome.css file in my profile.)
