Debug javascript of firefox addon

Question

I am working on a firefox addon which is heavily built on javascript. Addon is a ui recorder which has a popup window consisting of the addon specific buttons operating on a tab of main window.

When I inspect the debugger of either of the wondows, I dont see the javascript of the addon to set breakpoint or inspect. How do I debug?

Note: I want to debug the addon.
