Stops web surfing until a Codeforces problem has been solved How it works: 1. Enter your Codeforces handle & preferred rating range (e.g. 800–1200). 2. The extension fetches unsolved problems from the Codeforces API tailored to your range. 3. Any attempt to visit a non-Codeforces site is blocked by a full-page overlay. 4. Solve the problem on Codeforces & the block lifts automatically. 5. A new daily challenge is assigned each day with a browser notification. Features: - Random unsolved problem selection using the official Codeforces API - Configurable rating range (min/max difficulty) - Automatic daily problem assignment with alarm-based scheduling - Real-time Codeforces login detection - Cached problem sets for fast offline access - Lightweight - only requests Codeforces API data, no user data collected or transmitted Perfect for: - Competitive programmers who procrastinate between practice sessions - Students preparing for contests who need enforced focus - Anyone using the "don't break the streak" method to stay consistent No tracking or data collection. Just you & Codeforces!
