Ahhh Mel.... the master of understatement.

I would ask those who believe there is a different set of results for FFX vs. IE to conduct the same experiment that I have.

Try your search with both browsers, using the *same* Data Center. There's a list of DCs here: http://www.vaughns-1-pagers.com/inte...ta-centers.htm

Open both IE and FFX, enter the IP address for the same DC in both. Enter your search terms in both IE & FFX, then submit the search, switch to the other browser and submit there too.

I have done this a dozen times, and have not once found any difference in SERPs whatsoever. The order of sponsored links changes, but we all know that they are supposed to change with each search.

In my view, saying that Google serves more relevant results For FFX than it does for IE is much like saying that Google's results are always more relevant in the morning than at night. Both statements are IMHO illusions.
