Is Ad Blocker safe?

Question

Is Ad Blocker safe?

Accepted Answer

Ad Blocker is high risk. Every hour, this extension fetches a ruleset from ad-blocker.co and hands it full control over which sites get blocked or allowed in your browser. The operator can push rule changes — including rules that allow previously blocked ad networks or block legitimate sites — without any update to the extension itself. Each time you visit google.com/search, this extension increments a counter. That count — along with how many times the extension has blocked something — is sent to the extension's operator once per hour as part of a routine filter-update request. The operator learns how often you use Google Search relative to other browsing.
