Automatically change Firefox's theme based on the time.

This is a simple Firefox WebExtension that allows you to automatically switch between your themes based on the current time.

Set Firefox to change the UI to a dark theme during the night and change back to a light theme during the day!

Automatically calculate and set sunrise/sunset times based on your geolocation, manually set the sunrise and sunset times, or change themes based on your OS system theme.
