I think that you need to access this website via HTTP and not via secure HTTPS, so Firefox forces https:// then you need to make an exception and load the site via http://.

I can't get it to work with HTTPS-Only enabled because the server appears to have a valid certificate installed (disabling HTO for this site doesn't work), so I need to disable this feature to be able to open the site via http://

With the newest Firefox, some Security Certificates have been disabled because of issues with new mal-ware. Can you check with the site on what Security Certificates they are using? (SSL and TSL encryption protocols)
