🔍 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
