Uninstalls an add-on, given its ID.

This API requires the "management" API permission.

This is an asynchronous function that returns a Promise.


var uninstalling =
  id,                  // string
  options              // object


string. ID of the add-on to uninstall.
object. Object which may contain a single property, showConfirmDialog. If showConfirmDialog is true, the browser will show a dialog asking the user to confirm that the add-on should be uninstalled.
  • If id is the calling add-on's ID, showConfirmDialog defaults to false.
  • If id is a the ID of a different add-on, this option is ignored and the confirmation dialog is always shown.

Return value

A Promise that will be rejected with an error message if the user canceled uninstall.

Uninstall the add-on whose ID is "my-addon-id", asking the user to confirm. In the callback, check whether the user canceled uninstallation.

Note that we haven't passed a fulfilment handler because if uninstallation succeeds, the add-on is no longer around to handle it.

var id = "my-addon-id";

function onCanceled(error) {
  console.log(`Uninstall canceled: ${error}`);

var uninstalling =;
uninstalling.then(null, onCanceled);
