萤火虫返回不变nsLoginManager错误

我工作的一个项目，和Firebug的不断上报nsLoginManager错误（这无关我的项目。萤火虫返回不变nsLoginManager错误

这是令人不安的，看看在状态“3个错误”栏上我的浏览器只打开它，看看它的艾芬nsloginmanager错误消息。再次

以下是错误：

[Exception... 
"Component returned failure code: 0x80004001 (NS_ERROR_NOT_IMPLEMENTED) 
[nsIRequest.name]" nsresult: "0x80004001 (NS_ERROR_NOT_IMPLEMENTED)" 
location: "JS frame :: file:///Applications/Firefox.app/Contents/MacOS/ 
components/nsLoginManager.js :: anonymous :: line 315" data: no]file:/// 
Applications/Firefox.app/Contents/MacOS/components/nsLoginManager.js 
Line 315

下面是相关代码的形式nsLoginManager.js：

 onStateChange : function (aWebProgress, aRequest, 
           aStateFlags, aStatus) { 

     // STATE_START is too early, doc is still the old page. 
     if (!(aStateFlags & Ci.nsIWebProgressListener.STATE_TRANSFERRING)) 
      return; 

     if (!this._pwmgr._remember) 
      return; 

     var domWin = aWebProgress.DOMWindow; 
     var domDoc = domWin.document; 

     // Only process things which might have HTML forms. 
     if (!(domDoc instanceof Ci.nsIDOMHTMLDocument)) 
      return; 

     this._pwmgr.log("onStateChange accepted: req = " + 
         (aRequest ? aRequest.name : "(null)") + 
         ", flags = 0x" + aStateFlags.toString(16)); 

     // Fastback doesn't fire DOMContentLoaded, so process forms now. 
     if (aStateFlags & Ci.nsIWebProgressListener.STATE_RESTORING) { 
      this._pwmgr.log("onStateChange: restoring document"); 
      return this._pwmgr._fillDocument(domDoc); 
     } 

     // Add event listener to process page when DOM is complete. 
     domDoc.addEventListener("DOMContentLoaded", 
           this._domEventListener, false); 
     return; 
    }, 

    // stubs for the nsIWebProgressListener interfaces which we don't use. 
    onProgressChange : function() { throw "Unexpected onProgressChange"; }, 
    onLocationChange : function() { throw "Unexpected onLocationChange"; }, 
    onStatusChange : function() { throw "Unexpected onStatusChange"; }, 
    onSecurityChange : function() { throw "Unexpected onSecurityChange"; } 
},

我试过注释掉/删除文件的整个部分，只是为了让错误重新出现。

任何帮助将是完全的。
