Upon startup of Mozilla I get a popup configuration warning that states: "line 127: SyntaxError: unterminated string literal. user_pref("wa " No preferences user preferences are saved or called up. I have tried 1.0, 1.0.1, 1.1, and 1.2a and this problem happens on all versions.
This can happen if you system crashes or mozilla crasht while writing the prefs. you can do this : a) fix that error on profile/prefs.js b) create new profile -> invalid (no bug and this is no support databse)
