打开暂存器复制并粘贴此内容：

const nsIFilePicker = Components.interfaces.nsIFilePicker;

var fp = Components.classes["@mozilla.org/filepicker;1"]
               .createInstance(nsIFilePicker);
var startDir = FileUtils.File('C:\\');
fp.displayDirectory = startDir;

fp.init(window, "Dialog Title", nsIFilePicker.modeOpen);
fp.appendFilters(nsIFilePicker.filterAll | nsIFilePicker.filterText);

var rv = fp.show();
if (rv == nsIFilePicker.returnOK || rv == nsIFilePicker.returnReplace) {
  var file = fp.file;
  // Get the path as string. Note that you usually won't 
  // need to work with the string paths.
  var path = fp.file.path;
  // work with returned nsILocalFile...
}

如果你想要的东西让我知道，那么就把它放在默认位置
