I'm a tremendous fan of dark modes. They're easier on your eyes and your computer's battery, and I think make using sites and apps a lot more pleasant. Unfortunately, not every site offers a dark mode (this one included). However, this week I came across a web extension that can make the magic happen anywhere you want it to.
Called Dark Reader, the Chrome and Firefox extension creates a dark mode for websites on the fly, so no matter what site you're on you can browse without getting hit in the face with a bunch of white light.
The app essentially inverts the colours of sites while you browse, which may or may not be great, depending on what you're doing. You can create a custom list of sites that aren't affected by the extension, if you like, as well as customise things on a per-site level.
Out of the box it's admittedly not perfect (it does some crazy things to our highlighted stories carousel at the top of the homepage) you're still better off with a native dark mode. But, if you're doing some web browsing in bed and need things to be a little more subdued, or you want to conserve battery power on that long-haul flight, it could be just what the doctor ordered.
