[Greasemonkey] Debugging live/busy HTTP connections

In experimenting with this with a troublesome page, I found (after
*much* head scratching and speculation about what went wrong and how
to fix it) that replacing [\r\n]+ chunks for spaces prior to writing
the iframe would have the page load and fire the DOMContentLoaded
event as it should, but writing the iframe contents verbatim, would
just load indefinitely.

Is anyone here aware of any method, extension or hack to get an
overview of pending, busy and outstanding HTTP requests in firefox's
queues? The Live HTTP Headers extension lists what does get back to
me, but I'm rather interested in the opposite, what's left on the
queue before the throbber stops animating and my DOMContentLoaded
event will eventually fire.

This must be the first time in years I actually miss something from
Netscape 4, which had an easter-egg Ctrl+Alt+t shortcut to get a popup
with the URLs and state of presently busy connections.
