Old printer (Samsung, listed in my Important Modified Preferences in Troubleshooting) will not allow new printer to be Default printer. No matter what I do. I've followed the instructions here in FF Help re about:config & reset and others too. Is this something to do with FF? I've tried to find & delete the old printer all over my laptop, but it stays there like a bad penny as the default anyway. Is there a way to get rid of it by changing a code or something? Never had this problem before. I would appreciate any help you can give me. Kindest regards.

Here's a screen shot of the Samsung printer info in Troubleshooter .....Preferences. I don't know how to replace it w/ my new Canon. Samsung simply won't go away and won't let canon in. I've uninstalled & deleted it from every place I can think of. Thank you. ps: if I Refresh FF, will that help?

Sorry for another "Reply" -- also no prefs.js -- thank you

That dark-blue highlighted file is the prefs.js file!

Do { Ctrl + P } to open the "native print dialog" and up at the top where it says Printer > Name - select the other printer. Then proceed to printing a page from the dialog box. Now the "default" printer in Firefox is changed.
