草案
此页面不完整。

注意： This method is not available from Web content. It requires elevated privileges to access.

XMLHttpRequest.mozBackgroundRequest is a Boolean, indicating if the object represents a background service request. 若 true , no load group is associated with the request, with security dialogs prevented from being shown to the user.

In cases in where a security dialog (such as authentication or a bad certificate notification) would normally be shown, this request fails instead.

注意： This property must be set before calling open() .
