Interesting.

• openssl s_client -ssl2 fails, because SSLv2 is disabled
• openssl s_client doesn't enable compression
• openssl s_client -tls1 or -ssl3 enables compression

So I guess if client is using SSLv23_client_method() instead of
SSLv3_client_method() or TLSv1_client_method() it doesn't work. Also
Thunderbird uses Network Security Services library instead of OpenSSL,
so it might not support compression at all.
