No firewall but the Windows one. Disabling it has no effect; thunderbird still hangs. Process Explorer tells me that thunderbird has opened four local sockets (say port 2283-2286). 2283 connects to 2284, 2285 to 2286. All connections are in the "established" state. That's the case both when thunderbird and lightning work and when they hang.
