The source code is clean and directly implements the stated purpose: passively listens for popup messages and returns resource URLs from the DOM; uses those URLs to look up domain ownership in DuckDuckGo's public Tracker Radar dataset on GitHub ([domain withheld]) and displays results — no user data is sent anywhere. The ML signals (js_appendchild, html_hidden_elements) map to standard DOM manipulation for building the results list UI, not malice. The sole external network call carries only publicly-visible domain names as a path component to a well-known open dataset. The only meaningful concern is the publisher: other extensions flagged as malicious (100%) is a strong reputational red flag that prevents a clean false_positive verdict, but it does not override the absence of any malicious code pattern in this specific extension. Third-party chrome-stats corroborates the benign assessment (Impact, Likelihood).
