Firebug 1.5 actually contains support for activity-observer and
utilizes it mainly to get
precise timings for the Net panel timeline (you need to run with
Firefox 3.6).
See my blog post:

As far as the network response is concerned, you should be able to get
it
using the Net panel listeners even in Firefox 3.5.

Panel will be adding support for activityDistributor/
nsIHttpActivityObserver ?
