Field Unlocker is a free Chrome extension designed for developers, testers, and everyday users seeking to regain control over input fields on websites. This tool effectively removes readonly and disabled attributes from form elements, facilitating easier interaction with text fields, textareas, and selects. By doing so, it enhances the user experience, allowing for quicker data entry and better accessibility, especially on sites that impose restrictions on standard input behavior.

The extension operates by scanning the current webpage and unlocking interactive elements, enabling their editing and testing without altering site code. Key features include enabling browser autocomplete and password managers, which are often hindered by input restrictions. Additionally, users can easily toggle the extension on and off, making it a versatile solution for both development and regular web browsing, ensuring seamless interaction with form fields.
