What is this for?
When I set my theme to dark in Firefox, I expect a dark theme. This program will make the Firefox dark theme darker. It changes most, if not all UI elements that are white to another, darker, easier on the eyes color.
For instance,
POPOUT WINDOW
NEW TAB PAGE
Simply download, run, press 'y' and return.
