Automatic Theme Switching for Firefox

AutomaticDark is a Firefox WebExtension designed to enhance user experience by automatically switching themes based on the time of day. This tool allows users to set their browser to a dark theme during nighttime and revert to a light theme during daytime, promoting comfort and reducing eye strain. The extension calculates sunrise and sunset times based on the user's geolocation, ensuring that the theme changes occur seamlessly throughout the day.

Additionally, users have the flexibility to manually adjust sunrise and sunset times, or opt to change themes based on their operating system's theme settings. This subscription-based personalization tool is ideal for those looking to maintain a consistent aesthetic while browsing, adapting to both day and night environments effortlessly.
