setting default printer for firefox

more options

I am running Windows 10 Pro 2019 upgrade. My default printer is set in control panel to my Canon MF260 and is automatically selected by several apps, word, wordperfect, excel etc., however Firefox always selects another printer a Canon iP7250 colour that I don't use often, so each time I want to print an email I have to remember to select my default printer before printing. There seems to be nowhere in the Firefox setup to set the default printer.

Per /questions/1069672, The default printer is the last used printer. If you change to a different printer, Firefox should remember that one as the new default. If that setting has been turned off, turn it back on in about:config. print.save_print_settings


If that doesn't stick, per /questions/1000848, you can try Resetting a certain Firefox printer setting and Resetting all Firefox printer settings.

Hi Andrew,

Thanks for your help, but where can I find "about:config" Its not in Firefox Options or Customise?

It seems to me that Firefox ought to have a specific setting for a default printer as word processors do.

David,

You can access about:config by simply typing it in your address bar and pressing enter.

The "last used" printer is the default printer.

about:config provides a way to inspect and change Firefox preferences and settings which aren't part of the user interface = somewhat "hidden settings".
