30 Sep 08 Same search term for Google - Different Results in two different Browsers

Ok, I heard about this but never eperienced it. I searched for the term “Christ Church” and got to different SERPs from two different browsers. Any SEO guys got any ideas.

I searched the exact same term in both Safari and Firefox. In the Safari browser “Christ Church Nashville” is listed first in the FireFox browser “Christ Church Philadelphia” is listed first.

Any smart SEO guys want to weigh in I am listening. Also notice the other results are not the same. Looking for comments.
