Nord color theme

[ulipo]

The default dark color scheme doesn't blend in with the Nord GTK4 theme I use (applied with Gradience app)

I changed dark.css to use the Nord dark colorpalette, now Firefox blends nicley with the rest of the system

I don't think this is worth a pull request, I just past here the modified file, feel free to integrate it if you like:

@namespace xul url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");

/* Variables that start with --gnome- are added by me and are assigned
 * to elements somewhere in this code. The rest of the variables are
 * built-in in Firefox, so you need to add an !important if you wanna
 * override them. */
