"Tamper data" is the technique of intercepting and modifying the data sent between your browser (client) and a web server. An HTTP request is essentially the browser asking the server for something—like loading a webpage or submitting a login form. An HTTP response is the server's reply, which could be the requested page, some data, or a confirmation message. Tools like the "Tamper Data" extension, originally a popular Firefox add-on, gave users the ability to pause these transmissions, inspect the contents, and alter them before they reached their destination.
