Codeforces Get Friend's Status szerző: Shubham Verma

Never Ask Yourself 'Didn't I Do This Already?' Again!
A lot of us have an alternate account on codeforces, but maintaining what problem have been solved on the alternate account is very hectic. Imagine spending half an hour to solve, only to know, it was already solved by you.
So, this extension help to avoid that mistake.
Steps to setup:
Step1) Now go to the Codeforces problemset page and open any problem on that page(ex| https://codeforces.com/problemset/problem/1977/E).
Step2) Click on the "Get friend's status" extension, you can pin the extension for the ease of access.
Step 3) Fill the HandleName whose submission status you want to monitor and press submit.
Step 4) Right Click the extension (In FireFox the options comes up only when you are already on the problem page) and select "Always Allow on codeforces.com", after that, it will automatically.
Step 5) Refresh the page, the Status should be visible now.
Now, when you solve a problem, you will be treated with the information i.e the other user have solve that problem or not.

HAPPY CODING ;)
