External Links Detector is a Chrome extension designed to detect and unhide external links, making it an essential tool for combating hidden malicious links in user comments and posts. The extension inspects visited webpages, highlighting all external links, including those hidden through various techniques such as blank characters, dots, or white-on-white text with injected CSS code.

An important feature of External Links Detector is its site-based functionality, requiring explicit enabling on specific websites. The extension offers customization options, allowing users to create an ignore list for domains, choose counter positions, enable auto-run to detect links automatically, and auto-highlight external links for easy identification.
