Attachment: example wpad.dat file having issues

Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.15) Gecko/20110303 Firefox/3.6.15 ( .NET CLR 3.5.30729)

I've seen a number of bugs (Bug 558253, Bug 558253, Bug 223403, etc.) on myIpAdddress(), but I don't think any of these match my current issue; if I knew what result myIpAddress() was returning, I could comment under the correct bug (if relevant).

Attached is an example wpad.dat (or proxy.pac, take your pick) used in our standard autoproxy configs.  This works perfect on IE, but only "mostly" works for our FF users.  On my machine, I only have one IP address (so not issue with first IP being grabbed), and I'm not using IPV6.  The only other possible issue, if this is a reported bug, is that it might be returning 127.0.0.1, but I don't know how to verify this.

Running through various iterations of the wpad.dat file, I can confirm that it is definitely the if statement that is causing problems (changing default fail flips result back and forth).
