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.


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



An object with the following properties:

tabId Optional

integer. Specify the tab to get the title from.

windowId Optional

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.

Browser compatibility

BCD tables only load in the browser


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(() => {
  let gettingTitle = browser.browserAction.getTitle({});
