Clears a notification, given its ID.

This is an asynchronous function that returns a Promise.


let clearing = browser.notifications.clear(
  id                            // string



string. The ID of the notification to clear. This is the same as the ID passed into notifications.create()'s callback.

Return value

A Promise that will be fulfilled with a boolean: true if the notification was cleared, or false if it was not (for example, because the notification referenced by id did not exist).

Browser compatibility

BCD tables only load in the browser


This example shows a notification when the user clicks a browser action, unless the notification was already being shown, in which case it clears the notification:

let myNotification = "my-notification";

function toggleAlarm(all) {
  if (myNotification in all) {
  } else {
    browser.notifications.create(myNotification, {
      "type": "basic",
      "iconUrl": browser.runtime.getURL("icons/cake-48.png"),
      "title": "Am imposing title",
      "message": "Some interesting content"

function handleClick() {
  let gettingAll = browser.notifications.getAll();
