Hi,

I also observed this inconsistent behavior of Google. I see that visitor saw my site at the first page, but pasting the referrer URL into address bar in IE does not show my site even at the next few pages.

That is what I see as a referrer in my web log:
http://www.google.co.nz/search?clien...=Google+Search

So, this is the fact that Google treats Firefox in a special way.

Taking into account that Firefox is a kind of rebel, I do not exclude the possibility that this Google's behaviour is just another kick to Microsoft's guts.
The only question remains: would web surfers use Firefox-Google or IE-Microsoft?
