Title:
  System proxy settings doesn't work in Firefox when URL is a numeric IP
  address

Status in The Mozilla Firefox Browser:
  Fix Released
Status in “firefox” package in Ubuntu:
  Confirmed

Bug description:
  [Impact] 
  When entering URLs with IP adresses in Firefox, those IP addresses are not matched correctly to the "ignore hosts" setting, when having configured Gnome proxy settings and using "Use system proxy settings" in Firefox, because the IP addresses get converted to IPv6 but not the netmask/prefix.

  [Test Case]
   1. Set up a fake/invalid HTTP proxy server in Network options from 
      "System Settings->Network->Network Proxy "
   2. Try to go to google.com (make sure it's not https if you only set a http proxy)
   3. Try to go to 173.194.36.14 (use "ping google.com" to see IP)

  Actual Results:
      Google.com fails (which is good); but 173.194.36.14 succeeds
  Expected Results: 
      They should both fail with a non-working proxy server
  Note:
    doing this "backwards" because it's easier to reproduce on you don't have to care about having a real proxy server.

  [Regression Potential] 
    * None that I could see.

  [Other Info]
    * The patch is pulled from https://hg.mozilla.org/mozilla-central/rev/b936f0735ad8 .
