{{AddonSidebar()}}

Gets information about all open windows, passing them into a callback.

This is an asynchronous function that returns a Promise.

Syntax

let gettingAll = browser.windows.getAll(
  getInfo                // optional object
)

Parameters

• getInfo {{optional_inline}}

  • : object. This controls what {{WebExtAPIRef('windows.Window')}} objects are retrieved.

    • populate {{optional_inline}}

      • : boolean. Defaults to false. If set to true, each {{WebExtAPIRef('windows.Window')}} object will have a tabs property that contains a list of {{WebExtAPIRef('tabs.Tab')}} objects representing the tabs in that window. The Tab objects will contain the url, title and favIconUrl properties only if the extension's manifest file includes the "tabs" permission or host permissions that match the tab's URL.

    • windowTypes {{optional_inline}}

      • : An array of {{WebExtAPIRef('windows.WindowType')}} objects. If set, the {{WebExtAPIRef('windows.Window')}} objects returned will be filtered based on their type. If unset the default filter is set to ['normal', 'panel', 'popup'], with 'panel' window types limited to the extension's own windows.

Return value

A Promise that will be fulfilled with an array of {{WebExtAPIRef('windows.Window')}} objects, representing all windows that match the given criteria. If any error occurs, the promise will be rejected with an error message.

Browser compatibility

Examples

Log the URLs for the tabs across all "normal" browser windows. Note that you'll need the "tabs" permission or matching host permissions to access tab URLs.

function logTabsForWindows(windowInfoArray) {
  for (const windowInfo of windowInfoArray) {
    console.log(`Window: ${windowInfo.id}`);
    console.log(windowInfo.tabs.map((tab) => tab.url));
  }
}

function onError(error) {
  console.error(`Error: ${error}`);
}

browser.browserAction.onClicked.addListener((tab) => {
  browser.windows
    .getAll({
      populate: true,
      windowTypes: ["normal"],
    })
    .then(logTabsForWindows, onError);
});
