> For test purpose you need to use standard modern Firefox and connect to
normal validated https site that negotiate exactly the same cipher suite
as described (TLS1_TXT_DHE_RSA_WITH_AES_256_SHA)?
Sounds like a good idea. The challenge would be finding a website that is
(1) HTTPS, (2) blocked in Ethiopia, (3) negotiates
TLS1_TXT_DHE_RSA_WITH_AES_256_SHA.

result?
I ran a test where I asked the user to visit a blocked website, without
Tor, and capture the traffic with Wireshark. I don't know if the site
he/she visited negotiated the same cipher suite, though. The result was
that the user got a message saying the connection had been reset. This is
the same message you get if you visit baidu.com and search for a term you
know is blocked in China.
