How to access incremental script content in Firefox console?

Question

I developed an add-on for Firefox and Chrome. He has content scripts. I want to access them in the browser console (in Firefox web console ). For example, I want to enter a global variable defined in the script (s) content and output its value.

In Chrome, I can open the console by clicking F12, then go to the Console tab in the developer tools. It has a dropbox right after the filter button to select in which context I am participating (page / content script):

In Firefox, how to do the same?
