複製/粘貼的解決方案。享受

function DownloadFile(sLocalFileName, sRemoteFileName) 
{ 
    var saveToDirectory = 'C:\\Users\\louis\\downloads\\'; 

    var chrome = require("chrome"); 

    var oIOService = chrome.Cc["@mozilla.org/network/io-service;1"].getService(chrome.Ci.nsIIOService) 

    var oLocalFile = chrome.Cc["@mozilla.org/file/local;1"].createInstance(chrome.Ci.nsILocalFile); 
    oLocalFile.initWithPath(saveToDirectory + sLocalFileName); 

    var oDownloadObserver = {onDownloadComplete: function(nsIDownloader, nsresult, oFile) {console.log('download complete...')}}; 

    var oDownloader = chrome.Cc["@mozilla.org/network/downloader;1"].createInstance(); 
    oDownloader.QueryInterface(chrome.Ci.nsIDownloader); 
    oDownloader.init(oDownloadObserver, oLocalFile); 

    var oHttpChannel = oIOService.newChannel(sRemoteFileName, "", null); 
    oHttpChannel.QueryInterface(chrome.Ci.nsIHttpChannel); 
    oHttpChannel.asyncOpen(oDownloader, oLocalFile);  

} 
DownloadFile("saveAsThis.mp3","http://domain.com/file.mp3");
