Carrot: Codeforces Rating Predictor Add-on for Firefox

"Carrot" is a Firefox add-on designed to enhance the experience with Codeforces ranklists. During active contests, it calculates rating changes according to current standings, showing them in a new column, and for finished contests, it displays final deltas of each contestant. Also, it provides real-time data regarding the delta required to rank up. Its other features, such as toggling visibility of different columns according to the user preference, make viewing ranklists more manageable. Note that its accuracy varies due to the recent changes in the rating system.
