Proxy.pac file syntax is not correctly recognized in Firefox 4 final.

We are using a proxy.pac file to determine a proxy server based on subnet the user is in. (each subnet has its ISP and proxy server.)

here is the script:

function FindProxyForURL(url, host)
{
if (isInNet(host, "10.0.0.0", "255.0.0.0"))
        return "DIRECT";
if (isInNet(host, "127.0.0.1", "255.255.255.0"))
        return "DIRECT";
if (shExpMatch(url, "feed:*"))
        return "DIRECT" ;
if (shExpMatch(url, "ftp:*"))
        return "DIRECT" ;
if (shExpMatch( host, "localhost" ))
        return "DIRECT";
if (isInNet(myIpAddress(), "10.10.11.0", "255.255.255.0") || isInNet(myIpAddress(), "10.10.11.0", "/24"))
        return "PROXY 10.10.11.100:3128; DIRECT";
else if (isInNet(myIpAddress(), "10.10.12.0", "255.255.255.0") || isInNet(myIpAddress(), "10.10.12.0", "/24"))
        return "PROXY 10.10.12.100:3128; DIRECT";
else if (isInNet(myIpAddress(), "10.10.10.0", "255.255.255.0") || isInNet(myIpAddress(), "10.10.10.0", "/24"))
        return "PROXY 10.10.10.100:3128; DIRECT";
else
	return "DIRECT";
}

it seems like FF4 always pick the first proxy in "if" clause, and ignores the "else if" (i have tries to switch the proxies around.)

It was working correctly in FF3.6 and is still working in IE8.

System is Win 7 Ent. x64 bit. FF4 final.

Hi,

I have encountered the same issue and I have bypassed it as follow:

  1. about:config
  2. Search and set the option "network.dns.disableIPv6" to true

For my side, the options "use a PAC file" or "use system proxy settings" work with this change.

Bye. Francois

Well it did not worked for me. Still have the same problem.

Do you have multiple IP addresses on your client machine? If so, the myIpAddress() function returns only the IP of the first adapter it looks at. If you have wired, wireless, IPv6, etc addresses on your client, the myIPAddress() function will only return the first one it finds.

For example, if you are looking for an IP on a wired subnet, and your first adapter is wireless, the function will return the address of your wireless adapter, and the "else if" criteria will not apply.

This is still not working. And after upgrading to Firefox 6.0 the pac file does not work at all.
