Tamper Data

Continuing with my look at web developer tools for Firefox, today I want to tell you about Tamper Data. Tamper Data allows you to view and tamper with the HTTP request and response headers. Tamper Data is quiet a simple plugin. Once installed, simply go to the ‘Tools’ menu in Firefox and click the ‘Tamper Data’ menu item. Tamper Data will then open in a new window. In this state, Tamper Data will simply display any HTTP request as and when it happens. The table at the top gives you a list of requests. If you click one of the requests it will then display the full request and response header in the two frames below the table. If you click the ‘Start Tamper’ option, when the next HTTP request is activated a dialog box will give you the options ‘Tamper’, ‘Submit’ and ‘Abort Request’. If you click ‘tamper’, another window lets you change the request parameters and then continue with the request. Clicking the ‘Submit’ option will submit the request as it is, and the ‘Abort Request’ option will stop the request from being sent.

Tamper Data is useful to test the security of web applications by modifying POST parameters. Tamper Data also gives you other good diagnostic information, like the status code and the time taken for HTTP requests.
