Force Dark Mode

A global toggle switch to force dark mode on all websites using CSS inversion.

Force Dark Mode is a simple, lightweight browser extension designed to make any website easier on the eyes. With a single click on the toolbar icon, you can instantly switch a page into dark mode or return it to its original appearance. It works across most websites, including those that don’t offer a built-in dark theme, helping reduce glare and improve comfort during extended browsing. The extension focuses on ease of use. There are no complicated settings or menus—just a straightforward on/off toggle that does exactly what it needs to. Once activated, the dark theme is applied immediately to your open tabs, so you don’t need to refresh pages or revisit sites for it to take effect. Privacy is a core part of how Force Dark Mode operates. The extension does not collect, store, or share any personal data. It does not track browsing activity, read page content for analysis, or inject advertisements. Everything runs locally in your browser, ensuring your usage remains private. Only minimal permissions are required for the extension to function properly. It uses local storage solely to remember whether you last left dark mode enabled or disabled, so your preference is maintained between sessions. It also interacts with your open tabs only to apply or remove the dark theme instantly when you toggle it. Force Dark Mode is built for users who want a cleaner, more comfortable viewing experience without unnecessary complexity or data concerns.
