CF GetRating is a free Chrome extension developed by Manas Rawat. It falls under the category of browsers and specifically the subcategory of add-ons and tools. This extension allows users to easily view the rating of Codeforces problems, even if the problem tags are turned off.

The main purpose of CF GetRating is to provide users with the problem rating without the need to see the other tags associated with the problem. By simply installing the extension and turning off the "Show tags for unsolved problems" option on the Problemset page of Codeforces, users can view the problem rating directly. This is particularly useful for users who want to practice problems on Codeforces and want to know the difficulty level of a problem without explicitly knowing its tags.

In addition to displaying the problem rating, CF GetRating also includes a shortcut to go directly to the Contest Standings from the problem page itself. This feature allows users to easily navigate between the problem and the contest standings with just a click of a button.

Please note that the extension requires the Codeforces API to be functioning properly in order to work. It also does not work with problems that do not have a problem rating.

Overall, CF GetRating is a valuable tool for Codeforces users who want to conveniently view problem ratings without the hassle of dealing with tags.
