Tired of blinding white screens during late-night virtuals, I went looking for a solid dark theme. The classic scripts feel a bit too high-contrast with pure black backgrounds and the images still blinding , and the only polished modern extension I found was locked behind a $10 paywall.

So I put together my own standalone extension. It uses a softer dark palette (Zinc tones), renders MathJax formulas cleanly inline, and adjusts rating colors so they fit the background natively without straining your eyes. ### Preview

Installation

It's completely free and open source. It runs as a basic unpacked extension so the styles load instantly without lag.

You can download the ZIP and see the quick 30-second setup steps directly on the repo: Codeforces Dark Mode Pro on GitHub
