Localhost Warning

Ondřej Chlumecký

This extension helps developers easily recognize when they are working in a local or development environment by displaying a clear warning banner at the top of the page. 🚀 Features: ✅ Detects localhost, 127.0.0.1, .docker, and dev. domains. ✅ Displays a red warning banner with “This is a local or development page!” message. ✅ Prevents accidental modifications or actions in non-production environments. ✅ Works automatically on all web pages without additional setup. Perfect for developers, testers, and teams working with local or staging environments! 🔧 How to use: 1. Install the extension. 2. Open any local or development site (e.g., http://localhost, http://xxxx.docker, https://dev.xxxx). 3. See the warning banner at the top of the page. ⚠️ Note: This extension does not modify site functionality—it only adds a visual indicator to prevent mistakes.
