Cloudflare Optics is a browser extension developed by Cloudflare, Inc. that offers insightful connection and website information while you browse. It inspects the HTTP response details such as the HTTP version (1, 1.1, 2, or 3), data compression format, and server IP address of the sites you visit.

If a website is proxied through Cloudflare, Optics further enhances your browsing knowledge by revealing additional Cloudflare-specific capabilities in use, such as the presence of Cloudflare's WARP or Gateway services for enhanced security and privacy. Optics operates by locally analyzing incoming website responses and verifying if the site uses Cloudflare's proxy infrastructure. This extension enables users to gain transparency about their browsing connections in real time, ensuring they understand how Cloudflare infrastructure is impacting website delivery and security features.

By installing Cloudflare Optics, users agree to Cloudflare’s Terms of Use and Privacy Policy, ensuring ethical and secure operation. This tool is particularly useful for security-conscious users and developers looking to monitor web connection details and Cloudflare integrations conveniently from their browser.

Extension safety

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.

Cloudflare Optics requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Browser Add-ons, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Cloudflare Optics is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
