No Opener, No Phishers is a Chrome extension developed by Jamie Farrelly. It is a free add-on tool that aims to reduce the risk of falling victim to phishing attacks.

Many websites that use the target="_blank" attribute on their links, allow user-generated content, and do not use the rel="noopener" attribute on their links are vulnerable to a simple phishing attack. This extension serves as a solution to this issue.

Once installed, No Opener, No Phishers adds the "noopener noreferrer" attribute to the rel attribute on all links on the pages you visit. By doing so, it prevents you from becoming a victim of this type of phishing attack.

This Chrome extension is simple in its functionality, providing a straightforward solution to protect users from potential phishing threats. For those concerned about the security of their browsing experience, No Opener, No Phishers offers an open-source code on Github, allowing users to review and contribute to its development.
