FIXED IT!
The Web Site seemed to think I was in Korea! I couldn't even get to "www.freescale.com" as it would always give me a "404 Not Found":

I was also getting the following from the Error Console when clicking on the "Login" button:

The fix was to go into the Firefox "History", select one of the Freescale URLs, then say "forget this site". It wiped out ALL my browsing history for Freescale, and forgot my password cookie too. I can now get to the non-korean site and can log in.
