Features & Capabilities

Behind the Curtain is a powerful Firefox extension designed to help users uncover the backend IP addresses of websites protected by Cloudflare. Beyond just exposing IPs, it aggregates comprehensive website data by querying reputable sources such as crt.sh, Shodan, and IP-API. Users can also spoof the Host header to simulate requests from different domains, providing a practical means to bypass certain Cloudflare protections.

Developed with insightful features including favicon hashing based on MurmurHash3 to enhance discovery via Shodan, this extension is ideal for security researchers, IT professionals, and web enthusiasts who want to analyze site infrastructure and security setups. Its user-friendly interface combined with deep backend insights makes it a must-have tool for investigative browsing and security analysis. The extension credits the creator of its distinctive logo and openly utilizes existing open-source libraries to power its core functionality.

Is Behind the Curtain Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Behind the Curtain requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
