{{AddonSidebar()}}

Returns an array of the Window objects for each of the pages running inside the current extension. This includes, for example:

• the background page, if one is defined

• any popup pages, if defined and loaded

• any options pages, if defined and loaded

• any browser tabs that host content packaged with the extension

In Firefox, if this method is called from a page that is part of a private browsing window, such as a sidebar in a private window or a popup opened from a private window, then its return value will not include the extension's background page.

Syntax

let windows = browser.extension.getViews(
  fetchProperties // optional object
)

Parameters

• fetchProperties {{optional_inline}}

  • : An object with the following properties:

    • type {{optional_inline}}

      • : string. An {{WebExtAPIRef('extension.ViewType')}} indicating the type of view to get. If omitted, this function returns all views.

    • windowId {{optional_inline}}

      • : integer. The window to restrict the search to. If omitted, this function returns all views. In Firefox version 92 and earlier, sidebar views are not matched and, therefore, not returned.

Return value

array of object. Array of Window objects.
