PhishWall is a Firefox extension designed to enhance online security by protecting users from phishing attacks and malware threats. This subscription-based service requires both the main PhishWall program and the Firefox extension for full functionality. It provides visual indicators, such as a green signal, to confirm that users are on legitimate websites associated with PhishWall partner organizations. This feature helps users easily identify authentic sites and avoid potential scams.

In addition to phishing protection, PhishWall also offers safeguards against Man In The Browser (MITB) attacks. The extension checks for signs of MITB infections when users access premium partner websites. If any threats are detected, a warning message is displayed, and the extension can neutralize the virus to prevent unauthorized data input. This comprehensive approach ensures that users can browse the internet safely, reducing the risk of falling victim to online fraud.
