I needed to create a theme because:

A) many Firefox addons don't provide toolbar icons that can be easily seen on the background of dark Firefox themes

B) the lighter colored container names don't look so good against a lighter URL bar (otherwise I'm content with the Adwaita Dark theme contributed by EricEinar-1364597738.16)

C) I want to continue using the night theme switcher extension for GNOME, but I don't want to change Firefox theme when the system theme changes
