Phish Finder is a free Chrome add-on developed by Paul Lindquist, designed to help users identify and avoid potentially harmful links. As part of the browser's add-ons and tools category, Phish Finder aims to enhance online security by alerting users to links that should not be clicked on.

One of the main features of Phish Finder is its ability to display a "tool tip" for the actual URL behind a link. This provides users with valuable information about the destination of a link before they decide to click on it. By giving users this extra layer of transparency, Phish Finder helps to prevent users from falling victim to phishing attempts and malicious websites.

Additionally, Phish Finder prompts users for confirmation before redirecting them to external links within Gmail. This feature adds an extra level of protection for Gmail users, ensuring that they have the opportunity to verify the legitimacy of the destination before proceeding.

With Phish Finder, users can browse the web with greater peace of mind, knowing that they have an additional layer of protection against potentially harmful links. By leveraging the power of Chrome's add-on system, Phish Finder offers a simple yet effective solution to help users stay safe online.
