Gets details about a window, given its ID. The details are passed into a callback.

Note: If an error occurred (for example, because the window could not be found) then runtime.lastError will be set, and you should check for it in the callback.

  windowId,              // integer
  getInfo,               // optional object
  function(window) {...} // function

This API is also available as in a version that returns a promise.


integer. The ID of the window object you want returned.
object. Contains options to filter the type of window.
boolean. If true, the windows.Window object will have a tabs property that contains a list of tabs.Tab objects representing the tabs open in the window. The Tab objects only contain the url, title and favIconUrl properties if the extension's manifest file includes the "tabs" permission.
array of windows.WindowType objects. If set, the windows.Window returned will be filtered based on its type. If unset the default filter is set to ['normal', 'panel', 'popup'], with 'panel' window types limited to the extension's own windows.
function. The function is passed the following arguments:
A windows.Window object containing the details of the window.

Browser compatibility

Chrome Edge Firefox Firefox for Android Opera
Basic support Yes Yes 45.0 No 33


This example gets the current window and logs the URLs of the tabs it contains. Note that you'll need the "tabs" permission to access tab URLs.

Note: This example is a bit unrealistic: in this situation you would more probably use windows.getCurrent().

function logTabs(windowInfo) {
  if (chrome.runtime.lastError) {
  } else {
    for (tabInfo of windowInfo.tabs) {

chrome.browserAction.onClicked.addListener((tab) => {, {populate: true}, logTabs);
