LeetCode Submission Protection Firefox

LeetCode Submission Protection

Adds a confirmation step before submitting code on LeetCode, preventing accidental submissions and potential wrong answers.

Features & Capabilities

🔍 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)
  • Configurable via extension popup
  • Requires only LeetCode domain access
🚀 Installation & Usage
  1. Install from the Firefox Add-ons
  2. Open the popup and configure options:
  3. Enable / Disable protection
  4. Choose between Disable or Hide button
  5. Enable shortcut blocking
  6. Reload LeetCode — protection is active 🎉

Is LeetCode Submission Protection Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

LeetCode Submission Protection requires very minimum permissions.

Risk impact analysis details

  • Low ******* ****** ** *** ********* ******** ************
Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

LeetCode Submission Protection is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
