Uninstalls the calling add-on.

This API does not require the "management" API permission.

This is an asynchronous function that returns a Promise.


var uninstallingSelf =
  options              // object

Compatibility notes


  • 'dialogMessage' is not supported.


  • 'dialogMessage' is not supported.


Uninstall the add-on, 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.

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

var uninstalling ={
  showConfirmDialog: true

uninstalling.then(null, onCanceled);

The same, but also adding a custom message to the dialog:

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

var uninstalling ={
  showConfirmDialog: true,
  dialogMessage: "Testing self-uninstall"

uninstalling.then(null, onCanceled);
