[squid-users] Pressflow + Squid + Firefox = Not Working?

I'm having a strange problem with a test squid3 setup. Here's the stack:

Debian Etch
squid3-stable8
Apache2
PHP 5.2.6
Pressflow 6.19.96

Here are some relevant (I think) configuration lines from my squid.conf:

http_port 3128 accel defaultsite=hbc.carousel30.com
cache_peer 127.0.0.1 parent 80 0 no-query originserver

acl cookie_logged_in_set rep_header Set-Cookie LOGGED_IN=Y
cache deny cookie_logged_in_set
acl cookie_logged_in_out rep_header Cookie LOGGED_IN=Y
cache deny cookie_logged_in_out
acl cookie_logged_in req_header Cookie LOGGED_IN=Y
cache deny cookie_logged_in

acl forbidden http_status 403
cache deny forbidden

cache allow all

Now here's the weird thing - check this curl output:

* About to connect() to hbc.carousel30.com port 3128 (#0)
* Trying 10.1.1.30... connected
* Connected to hbc.carousel30.com (10.1.1.30) port 3128 (#0)

Looks like it worked, right? But check out these LiveHTTPHeaders from Firefox:

MISS every time! Safari is definitely HIT because it's coming back
lickety-split. Any ideas? Anyone seen this kind of thing before?
