Look for inspector.js file in the Firebug source base.
1) You are especially interested in startInspecting and stopInspecting
methods
http://code.google.com/p/fbug/source/browse/branches/firebug1.8/content/firebug/inspector.js#198
2) startInspecting calls attachInspectListeners method that register
bunch of listeners for key and mouse events
3) One of them is "mousedown" and "mouseover"
subWin.document.addEventListener("mousedown",
this.onInspectingMouseDown, true);
subWin.document.addEventListener("mouseover",
this.onInspectingMouseOver, true);
4) onInspectingMouseDown calls Events.cancelEvent(event); at the end
5) cancelEvent is implemented as follows:
Events.cancelEvent = function(event)
{
event.stopPropagation();
event.preventDefault();
};
So, every click is consumed by Firebug first and prevent links and
buttons to be active.
