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.
