Gets the sidebar's title.

Just as you can set the title on a per-tab basis using sidebarAction.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.sidebarAction.getTitle(
  details               // object


integer. Specify the tab to get the title from. If this is omitted or does not match the ID of an open tab, the non-tab-specific title is returned.

Return value

A Promise that will be fulfilled with a string containing the sidebar'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.sidebarAction.setTitle({title: "that"});
  } else {
    browser.sidebarAction.setTitle({title: "this"});

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