It would be helpful to look at the config of this pfSense box. Do his logs show 
any blocked traffic to/from your web server? Also, is it possible you're using 
an SSLv2 cert and the problem client is running Firefox 3 which by default has 
'issues' with SSLv2? If so, do a quick Google search for "firefox about:config 
security.enable_ssl2"
