Chrome Dark Mode Extension with No Performance Hit

Some dark mode extensions read and rewrite every color on a page after it loads, which takes work on large sites.

Modern Dark Mode keeps that small: it adds one CSS filter to the page and lets the browser draw it dark, and it does no other work while you browse beyond reading your settings when a page opens. No extension is completely free, though. A filter on a whole page is drawn by the browser's graphics pipeline, so on very long or animated pages an older computer may scroll a little less smoothly. If a site feels slow, exclude it in the popup.
