Chrome Autofill provides a convenient way to automatically fill forms on websites with saved addresses. The Autofill panel in DevTools lets you inspect the mapping between your form fields, predicted autofill values, and saved data.

Data and its mapping

The Autofill panel shows the data it inserted in the form fields and a table with mapping between the following:

  • Form field detected on the page.
  • Predicted autofill value, which Autofill determines using heuristics.
  • Value, if any, that Autofill inserted into fields it recognized.
