Dark Theme for Facebook™

This extension provides a native dark theme for both facebook.com and messenger.com. It applies the native coloring by altering the original colors to bring a dark appearance.

This theme is customizable from the options page. Also, the user can inject custom CSS styles into these websites to improve the styling and make it more personalized. You can turn the dark theme on and off from the toolbar button (action button). Also, it is possible to set a schedule (e.g., night-time duration only) to automatically turn the extension on and off.

Features:

1. Uses the original theme
2. Does not invert colors
3. Supports single-click on and off feature
4. Supports schedule on and off
5. Does not mess up the original theme
6. Supports user styling

-- Note that this theme is only meant to improve Facebook usage and has nothing to do with Faebook.com. It is a free, open-source project.
