We’ve just released a lightweight browser extension called Codeforces_Problems_Solved, developed with montassarbf
What it does Displays all rated problems solved by any Codeforces user, grouped by rating
Includes an interactive chart to explore solved problems by difficulty
Shows the full list of problems, not just counts
Key feature When viewing another user's profile, the extension highlights:
Problems you also solved
Problems you tried but didn’t solve
Problems you haven’t attempted 
This offers a detailed comparison — unlike existing tools that only show aggregate statistics.
Install it Download the ZIP from GitHub: github repository
Extract the folder
Go to chrome://extensions/
Enable Developer Mode → Load unpacked → Select the folder
Open any Codeforces profile to activate the extension
Why it’s useful This tool helps competitive programmers better track their progress, compare with others, and plan focused practice.
We’d love your feedback or suggestions on GitHub. github.com
