Cloudbleed Indicator for Chrome is an extension that detects or indicates if a web page is using Cloudflare. Cloudflare is a zero-cost service that secures a website by functioning as a proxy between the web servers and visitors. The service protects a site against malicious visitors, decreases average web page load times, and saves bandwidth. Cloudbleed is a bug that affected Cloudflare’s reverse proxies, which caused the servers to return memory that comprised private data such as authentication tokens, HTTP cookies, and other sensitive information.
