Details

So here it seems like the JS event loop is waiting for an event which is never dispatched.  This prevents Firefox from shutting down.

This is very bad.
That log does not indicate that FHR has received a shutdown request. Since FHR is not receiving a shutdown request, FHR never spins the event loop.

The FHR shutdown sequence is initiated when the "quit-application" notification is sent. Do you see anything in your logs indicating that "quit-application" or any part of the regular shutdown notification sequence is occurring?

Well, this is on the stack: http://mxr.mozilla.org/mozilla-central/source/toolkit/xre/nsXREDirProvider.cpp#864

So we send profile-before-change and then there's a JS handler which ends up calling nsThread::ProcessNextEvent at some point.  Is that not an indication of the FHR event spinning code?

I suspect this will be a dupe of bug 828149.
I'm very confident this is a dupe of bug bug 828149. Reopen if you can reproduce on m-c.
