It is difficult for users to diagnose proxy-related problems because the error page they get for a failed connection to the proxy is the same as the error they would get if they failed to connect to the website directly. We should tell the user that the error is due to a problem connecting to the proxy when the proxy connection fails.

Same problem here. The error message is wrong, and useful informations sent by the proxy are lost.

What does the proxy says (Wireshark):
=====================================

CONNECT docs.google.com:443 HTTP/1.1
User-Agent: Mozilla/5.0 (Windows NT 5.1; rv:2.0.1) Gecko/20100101 Firefox/4.0.1
Proxy-Connection: keep-alive
Host: docs.google.com

HTTP/1.1 407 Proxy Authentication Required
Proxy-Authenticate: NTLM
Cache-Control: no-cache
Pragma: no-cache
Content-Type: text/html; charset=utf-8
Proxy-Connection: close
Set-Cookie: XXXXXXXXXXXXXXXX=n; Path=/
Connection: close
Content-Length: 872

<HTML><HEAD>
...

What does (french-)Firefox says:
================================

La connexion a été refusée par le serveur proxy
Firefox est configuré pour utiliser un serveur proxy mais celui-ci n'accepte pas les connexions.

- Vérifiez que les paramètres du proxy sont corrects ;
- Contactez votre administrateur réseau pour vous assurer que le serveur proxy
fonctionne.

Poor translation:
=================

Proxy Server Refused Connection
Firefox is configured to use a proxy server that is refusing connections.

- Is the browser's procy configuration correct?
- Ask your network administrator to check that the proxy is working
