Good idea to use Wireshark--if I could afford the time.  It might
scare me enough to push me over the edge and ditch Firefox.

I run squid with a custom URL rewriter to block domains that have
have demonstrated behavior or content I find offensive.  Also, I
check (formerly /var/log/messages) and (now) /var/log/syslog and
observe a ton of blocked packets, mostly either

- outbound to port 19302 (IIRC) to 74.125.250.129 (Google)

- inbound from port 443 from DeepIntent and a few of its allies

- inbound ICMP from a ton of IP addresses

Being behind two NAT routers might account for some of the
above.  A friend suggested many of those packets might be content
providers trying to find a lower-latency "edge" host.
