The point of the exercise was to see what they would do in case someone searched for a competitor's product on their website, using the search bar left at default.

I'm just trying to point out that they're being kind of clever about firefox, since it's a hot, relatively new, competing product.

Also, I have had trouble accessing MSDN in the past with Firefox, so I could have been searching their site to find out why (I know better, but trying to justify why someone would actually do this...).
