SafeFill is a Chrome extension designed to enhance user privacy by revealing hidden input fields on webpages and preventing Autofill from populating these fields. It identifies various types of hidden inputs, such as those marked with "hidden" attributes or hidden via CSS, allowing users to see all data capture points. This transparency helps users understand what information might be collected by websites they visit.

In addition to visibility, SafeFill provides security features by blocking Google Autofill from automatically filling hidden fields with sensitive information. Users can customize settings to control which hidden fields are displayed, exclude certain websites from checks, and adjust highlight colors for better visibility. The extension also includes notifications for autofill actions and logging options for monitoring hidden fields, making it a valuable tool for those who prioritize data security and control online.
