If you open the page `about:config` and type in 'print.show_page_setup_menu' and change that preference to 'true', then you should get a 'Page Setup' item under the 'File' menu.

Jonathan, Thanks for trying, but this does NOT give me a Page Setup item in the File menu. I am using Firefox v97.0.1 (64-bit) on a Dell Inspiron with Intel Core i7-8700 CPU @ 3.20GHz. Does this help you at all?

Did you try to close and restart Firefox as that is required in some cases ?

Yes, I did restart the browser, but a Page Setup item did not appear in the File menu as expected.

This should work on Windows and Mac, it isn't available on Linux, so I can't test this.

#if !defined(MOZ_WIDGET_GTK)
                <menuitem id="menu_printSetup"
                          command="cmd_pageSetup" data-l10n-id="menu-file-print-setup" hidden="true"/>
#endif

It looks like you are throwing code at me, and I don't know what to do with it. Please give me step-by-step instructions. Thank you.
