813374 - Firefox ignores "Exclude simple hostnames" on OS X, when firefox's proxy settings are set to honour system settings

Status: RESOLVED DUPLICATE of bug 580530

(Firefox :: Untriaged, defect)

Description

[chee rabbits]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:16.0) Gecko/20100101 Firefox/16.0
Build ID: 20121024073032

Steps to reproduce:

Tested in 15, 16 and 19-Nightly.

Start ssh tunnel `ssh -D2000 [e-mail]`
Set apple macintosh's Network>Advanced>Proxies to SOCKS Proxy localhost:2000
Check "Exclude simple hostnames" in OS X network settings.
Set Firefox's advanced network settings to "Use system proxy settings".


Actual results:

Firefox correctly uses the proxy, but when attempting to connect to a http://localhost/ address it connects to server.lol instead of local machine. (same goes for 127.1/).

This can be worked around by adding "localhost" and "127.0.0.1" to OS X Network Settings or by manually configuring the proxy settings in Firefox. This is irritating if you're adding a lot of virtualhosts with different names :(


Expected results:

Firefox should be a good fox and not use the proxy for hostnames that seem local.

just realised this is a dupe.
it shouldn't be a wontfix though. 

>function FindProxyForURL(url, host)
>{
>   if(isPlainHostName(host)
>     || dnsDomainIs(host, ".internal"))
>   {
>      return "DIRECT";
>   }
>   else
>   {
>      return "PROXY 192.168.168.0.128:80";
>   }
>}


Something similar to this pac file should just come into action when exclude simple hostnames is checked.
