## Description

A lightweight security and privacy extension that does three things: strips ads at the network level so pages load faster, blocks analytics and tracking scripts that follow you across the web, and intercepts known phishing and malware domains before they load. Each tab gets its own blocked count, threats redirect to a warning page instead of loading silently, and you can whitelist any site instantly from the popup.
