Debug logging in Thunderbird's userChrome.js

Question

I'm trying to debug a custom javascript for Thunderbird that is defined in userChrome.js. Unfortunately I did not find a decent way to log to the javascript console. Is there an easy way to dump some information to an easily accessible console/logfile so that I can debug my script? I have console² installed and tried calling

throw Error("foobar");

already, without success.

Answer 1

Does Application.console.log("message") work?

Answer 2

1. Write console.log("hello"); in your *.uc.js file.
2. Open browser console(ctrl + shift + j).

Now, you can see message from file *.uc.js .
