ZAP by Checkmarx Browser Extension by Simon Bennetts

ZAP is a free OSS security tool which can be used to test the security of your web apps.
This browser extension will allow ZAP to gather more information about your app from the browser.
Most users should not install this extension.
It will be bundled in a ZAP add-on - this add-on will add the extension to Firefox when it is launched from ZAP.
