Print dialog box does not open. Print preview look ok, but cannot print from it either. Tried to reset with about:config, but print.print_printer does not show a file. Windows XP

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.

To Reset Firefox do the following:

  1. Go to Firefox > Help > Troubleshooting Information.
  2. Click the "Reset Firefox" button.
  3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
  4. Firefox will open with all factory defaults applied.


Further information can be found in the Refresh Firefox - reset add-ons and settings article.

print.print_printer in about:config is not exist if you've never used the printer, probably Firefox doesn't know it is installed on your system, see : Does not print to paper at all


thank you
