XSS for Firefox enables you to test XSS cross-site scripting, though it does not include testing for stored XSS.rnrn. To use this add-on, you will have to submit HTML forms and swap in strings that are representative of an XSS attack for the form value. When you have done so, the HTML page will establish a specific JavaScript value and mark your page as being vulnerable to the XSS string. Rather than compromising the security of your system, it seeks out vulnerabilities within your system.
