Is AdBlock — block ads across the web Safe? — Extension Safety Profile

This extension requests broad permissions typical of an ad blocker. The host access combined with scripting, webRequest, and webNavigation allows it to read and modify content on every website you visit. This is necessary to identify and block ad elements, but it also means the extension has the technical capability to see everything you do in your browser. The declarativeNetRequestWithHostAccess permission lets it block network requests before they load, which is a standard and efficient method for modern ad blocking under Manifest V3.

For any general browser extension that can read and alter all page content, a careful user should consider the publisher's trustworthiness and track record. The main safety consideration is that such powerful access, if misused or if the extension were ever compromised, could expose sensitive information like passwords or financial data. Users should verify they are installing the official version, as popular extensions are frequent targets for copycats and phishing attempts.

This extension's strongest dimension is Maintenance & Ownership, indicating it is actively updated and managed by a known publisher with a clean history. Its weakest dimension is Permissions & Access, reflecting the inherently high level of access required for its core function. The developer's privacy declarations state that data is not sold or used for unrelated purposes, which aligns with the extension's high Data & Privacy score.
