Hello everybody, i'm new to this forums, glad to be here...

I get different results form google with IE and Mozilla! How is this possible?
Also my PageRank (according to IE toolbar) shifted from 3 to 5 with the latest google shake, but my rankings in google are even lower.

I've come across something similar to this.

When I search for a keyword in Google.com via the IE browsers at college I get different results to those of when I search via Firebird at home.
