Hello Codeforces community!
Yesterday, I shared the initial version of Submity (a fork of the original extension) to help make submitting solutions faster. Since then, I've received amazing feedback, faced some critical bugs through github collaboration.
Today, I am super excited to announce a massive, highly stable update that completely transforms the UX of the extension.
What is Submity?
Submity adds a Submit option directly beside each problem description. You can paste your code and submit it without ever leaving the problem page.
What's New in this Update?
Live Verdict Tracker: No need to refresh the page or visit the "My Submissions" tab. Track your submission status (Testing, Accepted , Wrong Answer) live, directly beneath the submit button!
Zero Page Reloads: Submissions now happen seamlessly in the background via a hidden iframe. You stay 100% focused on the problem.
Cross-Browser Support (Firefox & Zen!): The extension now fully supports Firefox and Gecko-based browsers like Zen!
Safe API Usage: We've implemented strict rate-limit handling (3-second intervals and auto-pause on Error 429), ensuring you will never face any API timeouts or bans during contests.
How to Get It:
You can download the latest stable release (ZIP file) and check out the source code here:
LINK: https://github.com/sajibmrbitz/Submity-CF-2.0/releases/tag/v-2.0
(Note: Please refer to the README.md on the GitHub page for detailed, step-by-step installation instructions for Chrome, Edge, Brave, and Firefox).
If you like the extension, please consider giving the repository a star on GitHub. Feel free to contribute, report bugs, or suggest features!
Happy coding and wish you all many more Accepted !

Holy moly good extension
Thanks!! Use it during contests and let me know your feedbacks.
Thanks, brother. I have been using your first version and it has been very helpful. If I'm not mistaken, in your earlier version you replaced the "choose file from folder" option with a submit option where we could paste our code. I made a slight modification to your extension so that both the "choose file from folder" option and the submit option can coexist at the same time. I think it would be better if you could include this change in Submity 2.0.
Of course man! Just gimme a pull request so that I can merge it!! Looking forward to it
Thanks for the great extension! I wanna report a small bug with the submission id being commented in the code. It looks like the comment syntax is hardcoded to //, this works perfectly for cpp, java, kotlin and go, but it causes a CE in python.
I got two CEs because of this in yesterdays's contest, as I didn't test it out in practice first! Could you please update it to use language specific comment syntax in the next version? :)
Hadn't noticed that as I personally never used Py for CP. However, I updated the comment mechanism and the latest release now adds acceptable comments as per the language you have selected(c/cpp/java/kotlin/py/rust/ruby/go...) . Hopefully you'll never again face CE due to extension error. Let me know if you find any more bugs. Thanks!
The extension is super helpful. However, while I understand the whole point of this is so we can submit through it rather than going to submit page, if I do go to submit page while this extension is active, and click submit, it does not redirect me to submissions page. Sometimes, when I submit I like to check the exact case where answer is wrong or maybe even have a look at the hidden test case. Secondly, I was trying this in GYM but i went to submit page and submitted through the extension but the submission kept on loading with the text "Submitting" but even after waiting for 5 minutes i got nothing and when I refreshed, it was gone.
Thank you so much for the feedback and for pointing these out! You are completely right about the submit page. Currently, the extension overrides the default form globally which was part of my plan. I will think about updating it in the next release so that if you are explicitly on the submit page, it will behave normally (or provide a direct link to the details) so you can check the hidden test cases. For GYM contests, the Codeforces API handles user status slightly differently, which caused the tracker to get stuck. I will investigate the API endpoint for GYM and fix this integration as well. Thanks again for helping me improve the extension! Stay tuned for the next update.
