browsingData.removePluginData()

Clears data stored by browser plugins.

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

clear only plugin data stored after a given time
control whether to clear only data stored by plugins running in normal web pages or to clear data stored by plugins running in hosted apps and extensions as well.

This is an asynchronous function that returns a Promise.

Syntax

let removing = browser.browsingData.removePluginData(
  removalOptions            // RemovalOptions object
)

Parameters

removalOptions: object. A browsingData.RemovalOptions object, which may be used to clear only plugin data stored after a given time, and whether to clear only data stored by plugins running in normal web pages or to clear data stored by plugins running 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.

Examples

Remove data stored by plugins in 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
  .removePluginData({ since: oneWeekAgo })
  .then(onRemoved, onError);

Remove all data stored by plugins:

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

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

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