You’ll love this if you’re a fan of dark themes, or you work on a dark terminal (vim-hybrid, eh?) and switch to firefox often. Still not convinced, checkout the yeoman avatar ;)
Here’s the before view:

Next, get the Dark background and Light Text addon from firefox addons page. We’ll set the default mode to invert and colours from tomorrow night theme base colors.
Craziness.
