Secure connection messages indicate that Firefox cannot verify that the server responding to your request is really the one listed in the address bar. It is meant to protect against impostors.
The "MITM_DETECTED" message sometimes can be triggered by common security software. You might check the section corresponding to your security software in this article: How to troubleshoot security error codes on secure websites.
