CF Analytics is a Firefox extension designed to enrich the Codeforces user profile experience by providing insightful statistics about problem-solving activities. This tool features a 'Problem Rating' graph, which visually represents the number of problems solved categorized by their respective ratings, allowing users to easily gauge their performance across different difficulty levels. Additionally, a 'Tags Solved' graph offers a comprehensive view of the various tags associated with solved problems, displayed in a doughnut chart format, along with a detailed count for each tag.

Furthermore, CF Analytics includes an 'Unsolved Problems' section, which counts all attempted problems that did not receive a correct verdict, providing users with a clear overview of their challenges. The extension operates seamlessly within the browser and exclusively communicates with the Codeforces API, ensuring a smooth and efficient user experience.
