LeetCode Submission Protection by Sherukoda

🔍 What it Does

LeetCode Submission Protection is a lightweight browser extension that prevents accidental code submissions on LeetCode.

On LeetCode, a single misclick on the Submit button or pressing Ctrl+Enter / Cmd+Enter can instantly send your code — even if you’re not ready. This often results in:

• Wrong submissions saved in your profile
• Wasted attempts during contests
• Frustration when debugging

This extension adds a safety net so you only submit when you actually mean to.

⚡ Key Features

• Disable Submit Button – button stays visible but unclickable
• Hide Submit Button – removes the submit button entirely
• Block Shortcut Keys – disables Ctrl+Enter / Cmd+Enter submissions
• Lightweight & Fast – no performance impact
• Seamless Integration – blends with LeetCode’s interface

🎯 Why Use It?

• Avoid unwanted wrong submissions
• Take time to test properly before submitting
• Stay safe in contests, where wrong attempts cost points
• Works for both button clicks and keyboard shortcuts
• Zero setup — just install and go

🛠 Technical Notes

• Built with lightweight JavaScript (no heavy libraries)
