Finally figured out how to get Firefox into dark mode on Linux. I thought I could just set the browser theme to dark, but apparently that's not sufficient. I had to use gnome tweak tool to change my desktop UI to a dark mode, then set Firefox back to default.
I've no idea if that's how it works on macos or windows. I hope the choices become easy for users. I want to start programming sites that respect the choice.
@tomasino It's probably because of how Firefox interacts with GTK. It's a different behavior on Windows and Mac.
@tomasino Please, please, please devs make dark mode possible in everything everywhere.
