使用JavaScript从扩展程序中以编程方式打开Firefox浏览器控制台？

Question

I have tried attaching toJavaScriptConsole() to a button but this is not working (undefined reference error)

How can I program an XUL button to open the firefox browser console so we can see logs from the extension?

Answer 1

The following snippet will work.

if(HUDService.getBrowserConsole()) // is it already open?
  HUDService.getBrowserConsole().chromeWindow.focus();
else
  HUDService.toggleBrowserConsole();

Answer 2

If you are in a scope where HUDService is not available then to get access to it do the following:

var devtools = Components.utils.import("resource://gre/modules/devtools/Loader.jsm", {}).devtools;
var HUDService = devtools.require("devtools/webconsole/hudservice");
