Steps to reproduce:

1. Set dark mode theme on Firefox;
2. Reenable the Page Setup Menu (go to about:config and set print.show_page_setup_menu=true);
3. Open the Menu File \ Page Setup.

Actual results:

The Page Setup is unreadable under dark mode (see the attached images).

Expected results:

The Page Setup should be readable.

The Bugbug bot thinks this bug should belong to the 'Core::Printing: Output' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

We don't have non-native theme support for these so we can't use dark system
colors.

These look much nicer, and support dark mode.

Depends on D143903

Could you please stick to the default light theme instead of trying to change the Page Setup to a broken dark theme, then? It's better to be unconsistent than to be unreadable.

Or then change the Page Setup settings to be inside the print preview pane.
