Hi Codeforces Community,
I have made an extension to be able to practice speed problem solving on Codeforces.

It can set a timer within Codeforces site so that you get the native contest like feel but for an individual problem.
You can select different timers. Once selected, if you open any problem from Problem set or Contest it will automatically start the timer if it is a new problem for you.

I am not writing much here because I have already written instructions on the github repo.

Suggestions, improvements, and Pull Requests are welcomed!
Looking forward to hearing from the community

Thanks!
