I don't know where you are getting this I don''t see it in my google searches. I have The firefox search bar set to Google as the default and I don't get this.
Yes if I go to google.com first to make a search I get that and the slow increase in CPU to about 25%, if I play with the buckyball with the mouse pointer, spin it etc. yes it goes up a bit more but it doesn't get to anything like 60%
