Gets the browser action's title.

Just as you can set the title on a per-tab basis using browserAction.setTitle(), so you can retrieve a tab-specific title by passing the tab's ID into this function.

This is an asynchronous function that returns a Promise.


var gettingTitle = browser.browserAction.getTitle(
  details               // object


integer. Specify the tab to get the title from.
integer. Specify the window to get the title from.
  • If windowId and tabId are both supplied, the function fails and the promise it returns is rejected.
  • If windowId and tabId are both omitted, the global title is returned.

Return value

A Promise that will be fulfilled with a string containing the browser action's title.

This code switches the title between "this" and "that" each time the user clicks the browser action:

function toggleTitle(title) {
  if (title == "this") {
    browser.browserAction.setTitle({title: "that"});
  } else {
    browser.browserAction.setTitle({title: "this"});

browser.browserAction.onClicked.addListener(() => {
  var gettingTitle = browser.browserAction.getTitle({});
