I don't think Reiser4 is at fault here:

I found out that the Weatherfox plugin for Firefox had caused Firefox to
crash, and therefore every time I started Firefox the Quality Feedback 
Agent tried to send a message.

For some reason that didn't work, and the following entries showed up in 
Squid's access.log after a LONG time:

1094561818.215 1041126 127.0.0.1 TCP_MISS/504 1467 POST http://talkback.mozilla.org/spiral-bin/Collector.dll - DIRECT/207.126.111.208 text/html

Apparently the QFA continued to do this even after closing both its window
and Firefox, without any relevant processes showing up with ps..?!

Does this sound familiar?

After I uninstalled the Weatherfox extension the symptoms disappeared.

I'll try to reproduce it though..
