The about:config page is still there. Your Firefox indicated it is running on Windows 7. Is that accurate, or is it running on a new system in backwards compatibility mode?

Will the page open from the command line? In your system's Run dialog (Windows key + R) or in the system search box

  • on Windows 7, on the Start Menu
  • on Windows 10, on the Task Bar

try submitting this:

firefox.exe -new-window "about:config"

It worked and I was able to restore yahoo mail printing on my older HP Pavillion by typing "print-print" in the search tab once I opened "about:config" and deleting my printer, then restarting the computer. But when I deleted my printer on the HP Envy after using the "about:config " to access "print-printer" and hit the delete icon to the right of the printer name and then restarted Firefox after hitting the 3 line firefox at top right of screen and then hit "Exit" at the bottom it didn't work - still get huge "X" at top of yahoo mail "Print" page followed by black image of printer and then email right beneath that. Yahoo mail prints perfectly in Google Chrome, but only doesn't print in Firefox.
