I made a a Firefox-compatible fork of the [Contester](https://chromewebstore.google.com/detail/contester/iokpkljhlbiepgenceifefbdhbdcjknd) extension for Codeforces.↵

### Credits↵

Special thanks to the original author **[mrChest](https://codeforces.me/profile/mrChest)** for developing and publishing the original Contester extension. This fork aims to maintain compatibility with modern Codeforces and bring the toolset over to Firefox users.
