I can count bookmarks w00t

So I finally got the bookmark search to work BUT not with FUEL yet
var bookmarks = Cc["@mozilla.org/browser/nav-bookmarks-service;1"]
.getService(Ci.nsINavBookmarksService);

var history = Components.classes["@mozilla.org/browser/nav-history-service;1"]
.getService(Components.interfaces.nsINavHistoryService);
var query = history.getNewQuery();
query.setFolders([ bookmarks.bookmarksMenuFolder ], 1);
query.searchTerms = "developer";

var options = history.getNewQueryOptions();
options.excludeQueries = true;
options.queryType = Components.interfaces.nsINavHistoryQueryOptions.QUERY_TYPE_BOOKMARKS;

var result = history.executeQuery(query, options);

var root = result.root;
root.containerOpen = true;

for(var i = 0; i < root.childCount; i++) {
log(root.getChild(i).title);
}

root.containerOpen = false;

Well actually it did work with FUEL but I'm still trying to figure out how to read the results returned.
var query = Application.bookmarks.menu.newQuery();
query.searchTerms = "developer";

var result = query.execute();

var root = result.root;

for(var i = 0; i < result.length; i++) {
var x = result[i];
log(x);
}
Here the log prints out object, which is supposed to be an object of fuelIBookmark but it breaks when I try to log(x.title)
