FormyMcFormstein, developed by mcfr4g, is a free add-on for the Chrome browser that aims to make developing forms easier by enabling hidden form input elements. With this tool, developers can display hidden fields with just a click of a button.

By clicking on the FormyMcFormstein icon, hidden form input elements are revealed. These enabled fields are displayed in a pale blue color with a border, making them easily distinguishable from other form elements. This feature is particularly useful for debugging development, as it allows developers to quickly identify and inspect hidden fields.

One notable update to FormyMcFormstein is the addition of a context fix, which enables fields within sub frames. This enhancement further improves the functionality of the tool, ensuring that hidden form input elements are properly displayed across different frames.

Overall, FormyMcFormstein is a valuable tool for developers working with forms. Its simple and intuitive interface, combined with the ability to easily enable hidden fields, makes it a useful asset for debugging and enhancing form development.
