WWW Warn is a free Chrome extension developed by Header Inspector. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. This extension aims to protect users from phishing attempts by warning them when they access a domain that starts with "www" instead of the subdomain.

Phishing attacks have become increasingly sophisticated, with attackers registering popular domain names that mimic legitimate websites. By using a domain that starts with "www" instead of the expected subdomain, they deceive users into thinking they are accessing a trusted site. This extension helps to prevent such attacks by blocking requests to these suspicious sites and providing users with a fixed domain link.

One of the key advantages of WWW Warn is its commitment to user privacy. The extension collects no data and transmits no data, ensuring that users' information remains secure. By offering this valuable protection without compromising privacy, WWW Warn is a reliable tool for safeguarding against phishing attempts.
