Yahoo! has hidden this option way deep inside somewhere but I’m declaring it here in case there are people who want it anyway
1) Go to the address http://privacy.yahoo.com/privacy & click the “Cookies” link under the “Special Topics” column.
2) Click the “Web Beacons” link under the “Reference Links” Column.
3) On this page, click the “click here to opt out” link toward the end of the third paragraph under the “Outside the Yahoo! Network” title.
4) After a while, a page that says you have been out of the monitoring program will load. Without doing anything, close that page or continue your usual urfing by typing another address in the address bar. (Do NOT click the “Cancel Opt-out” button, your action will be cancelled!).
5) You’re done! Now Yahoo! will not record what you’re doing during surfing.
