ZAP Browser Extension is a free and open-source security tool developed by ZAP. It is designed to enhance the capabilities of ZAP in testing the security of web applications. This browser extension enables ZAP to access the client side of a web app, allowing it to gather more detailed information about the app directly from the browser.

ZAP, short for Zed Attack Proxy, is a widely-used security tool for identifying vulnerabilities in web applications. With the ZAP Browser Extension, users can leverage the full power of ZAP to thoroughly test the security of their web apps. By providing access to the client side of the app, ZAP can analyze the app's behavior, identify potential security flaws, and provide recommendations for improving the app's security.

It is important to note that the ZAP Browser Extension is not intended for general users. Instead, it is bundled as an add-on within ZAP itself. When launching ZAP from Firefox or Chrome, the add-on will automatically install the extension, enabling users to seamlessly integrate ZAP's powerful security testing capabilities into their web app development workflow.
