Free Manifest V3 Dark Mode Chrome Extension
Patrick Bushe · May 1, 2026
Chrome has been removing older Manifest V2 extensions, so it's worth picking one built for Manifest V3.
Modern Dark Mode is a free Manifest V3 extension. Like every Manifest V3 extension, it can't load code from the internet; everything it runs ships with it. It darkens every site with a CSS filter, keeps images and videos in their normal colors, and has an on/off shortcut (Alt+Shift+D), per-site exclusions, a schedule and Brightness, Contrast, Sepia / Warmth and Grayscale sliders.
