I have Firefox 11.0 and Apache-2.2.22 and OpenSSL 1.0.1a installed so
all of those protocols work correctly. You might want to consider
updating your "openssl" to the latest version. Unfortunately, you will
have to recompile everything linked against it. That can be trivial or
major depending on your system.
