The last response Squid got for that URL was cacheable for 24hrs and had no content. Squid is now serving that cached response until the 24hr storage time expires. Force a cache revalidation from the client (press Shift or Ctrl key while clicking the refresh/relaod browser button). I have tried that and the same happened, this time firefox didnt even made the frame petition.
This is sounding more and more like a firefox bug, or something hidden between your firefox and the Squid proxy. "smart" firewall or web AV scanner?
To have the request not even show up in the packets entering Squid shows its not entirely not a Squid problem.
What I tried next was to deny squid the caching of the regex 'ad-frame' . After applying that, the reply from the server is the same except that now I get: X-Cache: MISS from coruscant X-Cache-Lookup: MISS from coruscant:3128
Then the caching change has worked as intended. The content provided in MISS responses is what Squid gets from the upstream server.
