This toolbar will help you in testing sql-injection, XSS "holes" and the overall security of the site. This extension is not a tool for exploiting (from English - exploit) and it does not teach how to hack a site (or become a hacker). The primary role of the extension is to help developers verify the security level of their code. If you know what you need to do, then this panel will help make it faster. If you only want to learn how to find security gaps, then you can also use this panel, but you need at least a book and “many, many Google”. :) Download extension (For Firefox versions 1.5 - 2.0.0. *, But I think it will work with the modified version)
