CloudWarning

Many sites rely on Cloudflare for performance and security, but this comes at the cost of routing nearly all traffic through a third party often without users noticing. Because Cloudflare terminates TLS connections as a reverse proxy, it can technically see all data passing through, meaning the connection is not truly end-to-end encrypted.

The add-on scans each visited page for Cloudflare headers or resources and displays a clear warning when Cloudflare is involved. This helps users make informed decisions about their data especially on sites where they might submit personal information.

CloudWarning is not an anti-Cloudflare tool. It is a tool for digital sovereignty. By revealing hidden intermediaries and their potential legal obligations under U.S. law, it empowers users with the transparency needed to understand who handles their data and to act accordingly.
