+    4. Make sure your window has the globalOverlay.js script loaded.
+    5. To initialize the view
+        let view = new DownloadsPlacesView(document.getElementById("downloadsRichListBox"));
+        // This is what the Places Library uses. It could be tweaked a bit as long as the

+   *
+   * Returns an array of "migration resources" objects for the given profile,
+   * or for the "default" profile, if the migrator does not support multiple
+   * profiles.
+   *
+   * Each migration resource should provide:
+   * - a |type| getter, retunring any of the migration types (see
+   *   nsIBrowserProfileMigrator).
+   *
+   * - a |migrate| method, taking a single argument, aCallback(bool success),
+   *   for migrating the data for this resource.  It may do its job
+   *   synchronously or asynchronously.  Either way, it must call
+   *   aCallback(bool aSuccess) when it's done.  In the case of an exception
+   *   thrown from |migrate|, it's taken as if aCallback(false) is called.
+   *
+   *   Note: In the case of a simple asynchronous implementation, you may find
+   *   MigrationUtils.wrapMigrateFunction handy for handling aCallback easily.
+   *
+   * For each migration type listed in nsIBrowserProfileMigrator, multiple
+   * migration resources may be provided.  This practice is useful when the
+   * data for a certain migration type is independently stored in few
+   * locations.  For example, the mac version of Safari stores its "reading list"
+   * bookmarks in a separate property list.
+   *
+   * Note that the importation of a particular migration type is reported as
+   * successful if _any_ of its resources succeeded to import (that is, called,
+   * |aCallback(true)|).  However, completion-status for a particular migration
+   * type is reported to the UI only once all of its migrators have called
+   * aCallback.
+   *
+   * @note  The returned array should only include resources from which data
+   *        can be imported.  So, for example, before adding a resource for the
+   *        BOOKMARKS migration type, you should check if you should check that the
+   *        bookmarks file exists.
+   *
+   * @param aProfile
+   *        The profile from which data may be imported, or an empty string
+   *        in the case of a single-profile migrator.
+   *        In the case of multiple-profiles migrator, it is guaranteed that
+   *        aProfile is a value returned by the sourceProfiles getter (see
+   *        above).

+ *         - "bookmark"

+ *           @ URIList (Array of nsIURI objects) - optional, list of uris to
+ *             be bookmarked under the new folder.
+ *         - "livemark"
+ *       @ uri (nsIURI object) - optional, the default uri for the new item.
+ *         The property is not used for the "folder with items" type.
+ *       @ title (String) - optional, the default title for the new item.
+ *       @ description (String) - optional, the default description for the new
+ *         item.
+ *       @ defaultInsertionPoint (InsertionPoint JS object) - optional, the

+ *      Notes:
+ *        1) If |uri| is set for a bookmark/livemark item and |title| isn't,
+ *           the dialog will query the history tables for the title associated
+ *           with the given uri. If the dialog is set to adding a folder with

+ *           used ("[Folder Name]").
+ *        2) The index field of the default insertion point is ignored if
+ *           the folder picker is shown.
+ *     - "edit" - for editing a bookmark item or a folder.
+ *       @ type (String). Possible values:
+ *         - "bookmark"
+ *           @ itemId (Integer) - the id of the bookmark item.
+ *         - "folder" (also applies to livemarks)
+ *           @ itemId (Integer) - the id of the folder.
+ *   @ hiddenRows (Strings array) - optional, list of rows to be hidden
+ *     regardless of the item edited or added by the dialog.
+ *     Possible values:
+ *     - "title"
+ *     - "location"
+ *     - "description"
+ *     - "keyword"
+ *     - "tags"
+ *     - "loadInSidebar"
+ *     - "feedLocation"
+ *     - "siteLocation"
+ *     - "folderPicker" - hides both the tree and the menu.
+ *   @ readOnly (Boolean) - optional, states if the panel should be read-only
+ *
+ * window.arguments[0].performed is set to true if any transaction has
+ * been performed by the dialog.
