I blocked Firefox with Sunbelt Personal Firewall v.4.5 (formerly Kerio Firewall), by placing red X's on the four in/out points in the configuration. I noticed that the posted text messages on the Nascar Live Racecast on EPSN are still updating. I then blocked svchost.exe (out->Trusted), the only other thing enabled that's relevant, and the messages are still updating. (The only other thing allowed is completely unrelated, it's an independent application doing something else, and I don't want to kill that right now, or do a 'disable all traffic' in Sunbelt until it's done.)
Anybody heard of Sunbelt Firewall having such a huge, obvious hole? Is there something else that needs set?
UPDATE: I see the Firefox connections in "Overview" - they are all TCP connections to the standard port (HTTP), there are several. Blocking Firefox doesn't kill them, but it kills other pages loading, such as a different ESPN page, and it kills a loading Adobe flash movie. Those ESPN connections are not make if Firefox is blocked before loading that page. For some reason Sunbelt is failing to block those established connections.
