browsingData.removeFormData()

Clears data that the browser has saved for autofilling forms.

You can use the removalOptions parameter, which is a browsingData.RemovalOptions object, to:

  • clear only form data entered after a given time
  • control whether to clear only form data entered in normal web pages or to clear data entered in hosted apps and extensions as well.

This is an asynchronous function that returns a Promise.

Syntax

var removing = browser.browsingData.removeFormData(
  removalOptions            // RemovalOptions object
)

Parameters

removalOptions
object. A browsingData.RemovalOptions object, which may be used to clear only form data entered after a given time, and whether to clear only form data entered in normal web pages or to clear data entered in hosted apps and extensions as well.

Return value

A Promise that will be fulfilled with no arguments when the removal has finished. If any error occurs, the promise will be rejected with an error message.
