Firefox Add-on Builder extension debugging

Question

Hello I am using Firefox Add-on Builder for Firefox extensions. I am trying some basic code examples from their page, but I have a problem with logging simple text.

Firebug doesn't work as I read through Google, people recommended Firefox error console, but it gives me an errors instead of "text" from console.log.

I really need to somehow see what console.log returns for debugging purposes, otherwise I cannot make my extension :(

console.log only works using the Add-on SDK. There are various logging levels, but only console.error('message goes here') will show up in the regular browser error console screen that you have shown.
