The problem are following two rows in your chrome.manifest file:

You are using the same file (ff-overlay.xul, which is including
ff-overlay.js) to overlay two things (firebugOverlay.xul and browser.xul),
that's why it's executed twice.
You should:
- use firebugOverlay.xul if you want to overlay Firebug UI
- use browser.xul if you want to overlay browser window UI
