## Description

**Cloud Firewall** is a powerful Chrome extension that empowers users to selectively block connections to websites, pages, and web resources hosted on major cloud platforms such as Google, Amazon AWS, Facebook, Apple, Microsoft, and Cloudflare. Whether you want to prevent loading of entire sites or just third-party resources like images, videos, and scripts served from these cloud providers, this tool offers precise control.

With Cloud Firewall, toggling block settings is user-friendly via a popup menu, where you can enable or disable connections from any supported cloud service. By default, all connections are allowed, but users can customize rules per site or persist settings permanently in the advanced settings page. This extension enhances privacy and gives granular web resource control without affecting first-party content, making it ideal for users seeking stronger online privacy and resource management.
