It's ok, thanks.

Was hoping for the /full/ dark, where even the page bkg is all dark & stuff. But I guess this is alright, for now while I still search for a full "darkening" ffox theme that doesn't interfere with existing "page darkening" themes that don't work on Firefox pages and settings pages.

Maybe if I figure out how it's done, I'll call it "The Darkening".

Thank you so much for this -- and keep up the great work!
