Just got a used Dell Optiplex GX520 computer running Windows XP with a Canon printer. I can print from MS Word or MS Xcel fine, but keep getting a Crash message when using Firefox. Firefox was installed when I got the computer. I tried the "about:config" solution and there is no entry for "print_printer". Then I uninstalled Firefox, restarted the computer and re-installed Firefox. Tried printing and got the same problem.

Any suggestions on how to proceed.

Was the crash from Firefox? Or something else?

Give him these instructions;


Start Firefox in Safe Mode {web Link} by holding down the <Shift (Mac Options) > key, and then starting Firefox.

Stay in Safe Mode.

If you can't get Firefox to open, you will have to do this the hard way. https://support.mozilla.org/en-US/kb/mozillacrashreporter Open the file browser / explorer on your computer. Note: You may have to enable Show Hidden Folders / Files. Enter this in the address bar;
