Overview

This extension demonstrates a 'declarativeNetRequest' ruleset that blocks all requests to the domain 'example.com' on all frames.

🛠️ What It Does: This extension removes restrictive HTTP response headers such as: - X-Frame-Options - Content-Security-Policy - X-Content-Type-Options These headers often prevent websites from being embedded inside <iframe> elements. By removing them, this extension allows you to embed otherwise blocked pages—useful for developers, researchers, or anyone building iframe-based tools. 🔒 Privacy Friendly: - No tracking - No data collection - No cookies - Everything works 100% locally in your browser 🔧 Permissions Used: declarativeNetRequest – To modify HTTP headers *host_permissions: :/// ** – So rules apply across all websites These permissions are used only for modifying response headers. No browsing data or user information is accessed or stored. ⚠️ Disclaimer: This extension is meant for educational and development use. It may not work on all websites, especially those using advanced security techniques like frame-busting JavaScript or sandboxing. Always ensure you comply with the terms of service of the sites you interact with.
