Extension Metadata

About this extension
"Anti-Phishing Alert" is a Firefox browser extension designed to help users detect and avoid phishing websites. The addon automatically checks the URL of the site you're visiting. If it detects suspicious patterns—such as keywords like login, verify, secure, or uncommon domain endings like .xyz, .tk, etc.—it will display a clear warning banner directly on the page to help you stay safe and avoid data theft.
🔒 Key Features:
Automatic detection of suspicious URLs.
Visual alert banner shown on the suspicious webpage.
Option to close the tab immediately for safety.
Lightweight and doesn’t affect browsing performance.
🎯 Ideal for everyday users, office workers, and students—anyone who needs a simple but effective layer of protection while browsing the web.
