How to blacken all sites in Firefox

Question

Is there any way by which we can blacken all the sites which we open with a BLACK background color?

I have tried Stylish addon for Firefox. But I want to do it for many other sites like Google News, Google Maps and even Stack Overflow or Super User?

This should do the trick.

tools > options > content > colors > background

also uncheck the "allow pages to choose their own colors".

This userstyle is enabled for all pages by default: myfavolours. Related one two three.

I've asked about using colour profiles to achieve something similar, but that hasn't been done yet.
