Dark Mode for Wikipedia is a Firefox extension designed to provide a comfortable viewing experience for users of the English Wikipedia. This open-source tool allows users to toggle a dark theme, reducing eye strain during night-time browsing or in low-light environments. The extension is particularly tailored for the standard Wikipedia interface and may not function optimally for other domains. Currently, the developer is working on improving table coloring to enhance readability further.

The extension operates using two scripts: background.css, which manages the overall styling, and contentScript.js, which applies the dark mode to the content displayed on Wikipedia pages. As a subscription-based service, it aims to enhance user experience while browsing Wikipedia, making it a useful addition for those who frequently use the platform.
