Comment 6 for bug 113632

To reiterate what I've said, in many places, at many times, for better or worse
we're on the GTK2/GNOME integration train. We're not that platform independent,
we pick up GTK themes, and GTK button ordering, among other things.

To respect KDE prefs, we'd need an integration layer with KDE, and we'd want to
use KDE dialogs, and KDE theming, etc. There's a port for QT, it was back on
track at one point, but I'm not sure where that's going. Once its
production-ready, a Firefox KDE port is feasible, but until then we're basically
a GNOME/GTK2 app, like it or lump it.
