{{AddonSidebar()}}

Removes the specified browsing data.

The browsing data to be removed is specified in the dataTypes option, which is a {{WebExtAPIRef("browsingData.DataTypeSet")}} object.

You can use the removalOptions option, which is a {{WebExtAPIRef("browsingData.RemovalOptions")}} object, to control how far back in time to remove data and whether to remove data only from normal web pages or to remove data from hosted apps and extensions as well.

This is an asynchronous function that returns a Promise.

Syntax

let removing = browser.browsingData.remove(
  removalOptions,            // RemovalOptions object
  dataTypes                  // DataTypeSet object
)

Parameters

• removalOptions

  • : object. A {{WebExtAPIRef("browsingData.RemovalOptions")}} object, which may be used to control how far back in time to remove data, and whether to remove data from hosted web apps and extensions, or just normal web pages.

• dataTypes

  • : object. A {{WebExtAPIRef("browsingData.DataTypeSet")}} object, describing the types of data to remove (e.g. history, downloads, …).

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.

Examples

Remove download history and browsing history for the last week:

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

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

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

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

browser.browsingData
  .remove({ since: oneWeekAgo }, { downloads: true, history: true })
  .then(onRemoved, onError);

Remove all download and browsing history:

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

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

browser.browsingData
  .remove({}, { downloads: true, history: true })
  .then(onRemoved, onError);
