This freeware Firefox add-on helps Web site administrators easily test page post and header data exchange. Tamper Data's Firefox-based sidebar is very easy to install and operate. The program's online Help explains the app well enough to teach inexperienced site builders.
Tamper Data acts as a stop sign between data exchanged from a Web site and your browser. Data is exchanged normally until the Start Tamper button is selected. For each subsequent request, the utility pops up a dialog to poll the user to tamper with the data, submit it as normal, or cancel the request. The Tamper Popup is a clearly displayed, editable list of standard values requested by the Web site. Users edit the data as they see fit and click to send it to the Web site. It's easy to add elements to the data with a handy context-click menu. An options menu gives users extensive control over the context menu items.
Web site designers and administrators will find Tamper Data gives them much greater control over a standard browser function.
Use Tamper Data to view and modify HTTP/HTTPS headers and post parameters. Trace and time http response/requests. Security test Web applications by modifying POST parameters. FYI current version of Google Web Accelerator is incompatible with the tampering function of Tamper Data. Your browser will crash. This version is the first release on CNET Download.com.
