同步获取脚本时的NS_ERROR_FAILURE

Question

我收到此错误

"[Exception... "Failure" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: http://code.jquery.com/jquery-1.10.2.min.js :: .send :: line 6" data: no]"

执行此请求时

$.ajax({
    url: 'https://www.paypalobjects.com/js/external/dg.js',
    datatype: 'script',
    async: false,
    cache: true,
    //ifModified: true,
    type: 'GET',
    data: null,
    error: function(xhr, textStatus, errorThrown) { console.log(xhr, textStatus, errorThrown); }
})

有人可以复制吗？ Fedora 20中的Firefox 26
