Firefox throws an error related to security when connecting. How ironic.
"Secure connection failed
"The connection to www.openssl.org was interrupted while the page was loading."
What certificate do you see, and have you configured any security settings in your browser or installed any custom "security" solutions / MITM proxies on your computer? openssl.org supports only TLS 1.1 and v1.2, so it's possible that some older proxies, DLLs, etc. can interfere.
I already know there are some sites I can't use from the developer edition due to things like outdated/insecure cipher suites, but which continue to work in the released version and in other browsers.
