This is an add-on that lets you invert the website's color scheme by inverting/changing the prefers-color-scheme media feature of CSS without requiring you to change the whole system style setting.

You can also trigger toggling the dark mode with the hot key <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>B</kbd> (customizable in the Firefox add-on settings).

This extension only works with Firefox v95 or higher.


✍️ Usage ✍️

You can use a toolbar button to toggle whether it should force a dark mode or not. It displays a yellow moon icon, if it is enabled and forces the website to be dark.
