About this extension
Dark mode for every website, with almost no slowdown.

• Pages load dark from the first frame: no white flash.
• Sites that are already dark are detected and left alone.
• Turn it off for one site, or switch to “only the sites I choose”.
• Brightness, contrast and sepia sliders, plus a keyboard shortcut (Alt+Shift+D).
• No ads, no nag screens, no account, no tracking.

HaloDark makes no network requests. Your settings stay on your device.

Limits: HaloDark uses a fast colour-inversion filter rather than rewriting every style, so a few sites with unusual designs may look less polished than with heavier tools. Turn it off for those sites with one click.
