The major difference between previous version and current that in the previous version we always closed connection, even in 1.1, PHP streaming was not using chunked encoding explicitly and the server never auto-assigned it. In current version the server decided and because we always keep-alive and in chunked, Firefox after 3 request hangs because reply is not correct. This is strange because in telnet session it looks fine but my eye may not be protocol-demanding like Firefox.
