  首先，您必须获取要从中获取消息的窗口的innerID .

  使用sdk，您可以使用 var innerID = require("sdk/window/utils").getInnerId(require("sdk/view/core").viewFor(require("sdk/windows").activeWindow))

  或者更干净：

  var utils = require("sdk/window/utils");
  var viewFor = require("sdk/view/core").viewFor;
  var windows = require("sdk/windows");
  
  
  var innerID = utils.getInnerId(viewFor(windows.activeWindow));
  

  然后，您希望观察该窗口的控制台通知：

  var system = require("sdk/system/events");
  
  system.on('console-api-log-event', onMessage);
  
  function onMessage(subject) {
    subject = subject.wrappedJSObject;
  
    if (subject.innerID != innerID) {
      return null; //ignore this console log, because it is for a window/thing that I don't care about
    }
  
    if (subject.level != "log") {
      return null; // ignore anything but console.log, like: console.info, console.error, console.debug, etc.
    }
  
    var message = subject.arguments[0]; // first string argument to console.log()
    // do something with the console.log("") message
  }
