freeCodeCamp has a dark theme. If you use browser extensions that change the appearance of websites, then you need to turn those extensions off whenever you use that browser for web development because what you see with it on is not what your users will see. Also, you won’t pass freeCodeCamp tests because it changes the CSS after you write it.
freeCodeCamp should work on the most recent versions of Firefox, Chrome, Edge, and Safari. It’s the extension, not the browser.
