Thanks to the work of a number of helpful people I now know how to configure KDE plasma to allow Firefox to work in dark mode and support the CSS prefers-color-scheme feature. In KDE Settings search for GTK. This brings up the GTK Application Appearance panel. In here you can choose the GTK2 and GTK3 themes. Adwaita-dark is available for GTK2 but there are no GTK3 dark themes listed. I cannot find a GTK3 dark theme in the Fedora 30 repos. I had to install a dark theme from the Choose Theme button - I use Mojave-dark. Once I had done that Firefox come up in dark mode. Am I correct in thinking that there are no packages with a dark theme for GTK3 apps?
