Toggle dark mode

By: Cimbali
Toggle the content’s color scheme between preferring light or dark (or inheriting)

Features & Capabilities

Toggle Dark Mode is a minimal and powerful Chrome extension designed to easily cycle through content color schemes. By clicking the toolbar button, users can switch between dark, light, inheriting the browser's preferences, or inheriting the system's color scheme. The add-on requires minimal permissions, ensuring a lightweight experience.

The extension works best with websites supporting native dark and light modes like DuckDuckGo, Google, GitHub, and StackOverflow. For unsupported sites, users can incorporate custom styles via user stylesheet tools like Stylus combined with CSS media queries for prefers-color-scheme. Note that when strong fingerprinting protections are enabled in Firefox, this extension’s toggle may have no effect, as the browser conceals color preferences from websites. Enhance your browsing comfort quickly with Toggle Dark Mode!

User Reviews

Users praise the extension for being simple and effective at toggling the prefers-color-scheme (light/dark) for testing and development, and for its minimal permissions. It performs well on sites that support the feature. However, several reviews mention reliability problems, with the extension not working on some sites. A common request is to add more features like per-site dark/light presets and auto-refresh when toggling.
Pros
  • Simple, lightweight and easy to use.
  • Toggles the CSS media query (prefers-color-scheme) to switch between light and dark.
  • Minimal permissions / privacy-friendly.
  • Useful for web development/testing to preview dark/light modes.
  • Works on sites that support the prefers-color-scheme feature.
Cons
  • Reliability issues: not all users report it works on every site; it can fail on some sites.

Basically does what "about:preferences -> Website appearance" does. Absolutely chuffed.

THIS IS EXACTLY WHAT I WAS LOOKING FOR. If you need to see how your site looks on users with dark theme and light theme on their devices, this extension is the ONE. I believe this is the only extension that switches prefers-color-scheme and does not do anything extravagant. The only request is that I wish there was a shortcut key to this blissful extension.

Is Toggle dark mode Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Toggle dark mode does not require any sensitive permissions.
