A very basic add-on that inverts the colors of the website. Includes a Toggle Button.

Colors can also be inverted globally using the hotkey (alt+shift+r). Or only on the active tab using (alt+r).

Note that currently this extension does not work with Firefox on Android, as the "browser.tabs.insertCSS" api just does not work work on Firefox on Android.
