## Description

Policy Control is a powerful Chrome extension that lets users selectively enable or disable various web resources such as JavaScript, CSS stylesheets, images, media, fonts, and plugins including Flash. Designed as an alternative to the NoScript Security Suite, it allows detailed filtering rules per hostname to block third-party content, thereby enhancing privacy and security. Users benefit from advanced filtering settings to customize exceptions and improve browsing speed and bandwidth usage by blocking unwanted content like ads, trackers, and heavy media files.

The extension supports control over many resource types including fonts, images, media (audio/video), scripts, stylesheets, iframes, XMLHttpRequests, WebSocket connections, plugins, and more. It serves as an effective tool for users seeking granular control over their browsing environment to prevent tracking, reduce data usage, or disable distracting or intrusive elements.
