Competitive Companion
Description from store

Competitive Companion parses competitive programming problems and contests and sends the parsed data to various tools like CP Editor and CPH. At the moment it supports 116 online judges, including most major ones like AtCoder and Codeforces.

Using it is very simple. Just install the extension, make sure you got one of the supported tools open, navigate to a problem page and click on the green plus icon in the top-left of your browser. On websites where Competitive Companion is able to parse contests, navigating to the page with all the problems and clicking on the green plus icon will download and parse all problems in the contest at once. You can also use the Ctrl+Shift+U shortcut instead of the green plus icon (configurable on chrome://extensions/shortcuts).

So it's ok but I'd rather cf tool + neovim in terminal But if the question names instead of XXX_XXX.cpp was like 800B.cpp would be better and way easier

I love this as it saves a lot of time, But I am using Google Chrome. Submit directly from the VS code stuck in waiting. Is there any other extension I need to install in order to submit directly from the VS code to the Website(Codeforces, CodeChef);

This is the best and most important and must have extension for competitive coders. I cant say it in words enough, but this is epic epic epic epic epic... I just click on the Extension and it automatically adds the Test cases to my VSCode and also creates a separate file for any new code that I am solving. You have to combine this extension with one extension of of VScode(CPH Judge)...And u are in Coding heaven. Trust me It'll save a lot lot of time while in contest.
