In what sense? At the most general level, a firewall is a device which
resembles a router, and which can be configured to permit or deny certain
types of traffic between two or more networks.

Squid, on the other hand, is a proxy which accepts web and ftp requests
from clients and deals with them on the clients' behalf. What "dealing
with them" actually involves is pretty open-ended as Squid can be
configured in lots of different ways.

However, many firewalls also support proxying, including proxying of HTTP
traffic; if you are really looking at the difference between proxying HTTP
on a firewall and proxying HTTP on a Squid box then the difference is
simply that all the firewall proxies I've seen are simplistic non-caching
beasts, whereas Squid caches, is highly configurable, and much much
faster.

I hope this stab-in-the-dark helps.
