On a bookmark directly on the Personal toolbar you can get a context menu which enables you to amongst other things change the properties or open the bookmark in a new tab/window. However if you create a folder on the personal toolbar and add bookmarks into that folder you cannot get any context menus on items under that folder. It would be good if we could get context menus there as well.
