## Description

Form Hack is a simple yet powerful Chrome extension designed for web developers and testers. By adding a convenient button to the browser's address bar, it allows users to reveal all hidden input fields within an HTML page instantly. This functionality makes it easier to inspect and debug forms by showing hidden inputs that contain important data, such as those used in web forms for passing backend values or state without displaying them on the page.

The latest version of Form Hack enhances usability by displaying the name or ID attributes of each hidden input, providing clearer insight into the purpose and identity of these fields. This tool is ideal for anyone involved in web development, debugging, or security testing who needs to verify the hidden form elements without manually searching through the HTML source code.
