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

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.

Examples

Remove form data saved in the last week:

function onRemoved() {
  console.log("removed");
}

function onError(error) {
  console.error(error);
}

function weekInMilliseconds() {
  return 1000 * 60 * 60 * 24 * 7;
}

var oneWeekAgo = (new Date()).getTime() - weekInMilliseconds();

browser.browsingData.removeFormData(
  {since: oneWeekAgo}).
then(onRemoved, onError);

Remove all saved form data:

function onRemoved() {
  console.log("removed");
}

function onError(error) {
  console.error(error);
}

browser.browsingData.removeFormData({}).
then(onRemoved, onError);
