block "waiting for doubleclick" forever

Its like my computer is running a turbo now !

On IE6 it would be Tools > Internet Options > Privacy.
On Privacy page where it says 'web sites' click on 'edit', then type both 'doubleclick.com' and 'doubleclick.net' in the box and click Block for each one.
Click OK, Click OK.

On Firefox it would be Tools > Options > Privacy.
Where it says 'cookies' click on 'exceptions' and then do the same thing...

This works for all that "waiting for" junk when clicking from page to page.

Double click is some sort of marketing scam spam tracking site. wait 2 seconds for it,? wait an hour for this stupid double click for every 1800 pages you view.
