It seamlessly integrates into the CodeForces problem page, allowing you to instantly view accepted solutions from your friends without ever leaving the tab. Whether you are looking for a different approach, an optimization hack, or just inspiration, CF FetchCodes brings your friends' code directly to you. 🚀 New in this Update (v25.12.07): Smart Session Management: No more confusing "Failed to load" errors!

You can now retry fetching a specific code instantly without refreshing the entire page. - Enhanced Error Feedback: Clearly distinguishes between Hidden/Private codes (which can't be viewed) and Auth Errors (which just need a quick login). ✨ Key Features: 👀 Instant Code Access: See a list of all friends who have accepted the current problem. ⚡ Lazy Loading: To save bandwidth and speed up the page, code is only downloaded when you click a specific friend. 🛡️ Robust Auth Handling: Seamlessly handles background session timeouts, ensuring you can continue browsing friends' codes even if your login cookie expires. 🎨 Native Syntax Highlighting: Read code comfortably with coloring that matches the CodeForces environment (Supports C++17/20, Python 3, Java, and more). 🔗 Quick Navigation: Includes direct links to the original submission and your friend's profile. 📊 Progress Status: A real-time progress bar shows you the status of checking your friends' submissions. Safety-First Architecture: Uses "Human-Like" delays and randomized jitter to strictly adhere to CodeForces API limits and keep your account safe. 🛠️ How to use: Install CF FetchCodes. - Navigate to any CodeForces problem page. - Look for the "→ Accepted Codes of Friends" box in the right sidebar. - Click "Show Codes". - Click on any friend's name in the list to expand and study their solution! ⚠️ Important Notes: - Contest Integrity: To maintain fair play, this extension does not work during live contests. It is designed for practice and upsolving. - Privacy: You can only view submissions that are public. Private or gym submissions are restricted by CodeForces API rules. 🤝 Contribute & Support CF FetchCodes is an open-source initiative built by the community, for the community. We love pull requests!
