Browser Styles
This global dark style from user-styles is great ! Easier on the eyes. Use with the stylish plugin for FireFox :https://userstyles.org/styles/31267/global-dark-style-changes-everything-to-dark
UPDATE : The stylish plugin is said to snoop on you, collecting data. There are alternative plugins like stylus.
Another option is to use a plugin that allows you to execute JS on load, and inject your style sheets via that. e.g. the onload scripts extension for chrome : https://chrome.google.com/webstore/detail/onload-scripts/gddicpebdonjdnkhonkkfkibnjpaclok
