Prevent Yahoo! from Tracking Your Web Browsing or E-Mail Reading Habits

Yahoo! uses cookies and Web Beacons to track your surfing habits.

A Web Beacon is generally a 1x1 pixel transparent GIF image that can track if the user viewed a particular email message or a webpage. [related: Read Receipts in GMail]

According to their privacy policy, Yahoo uses Web Beacons to determine if you read the email message, display relevant banner advertising or record usage of sites that you surfed on the Yahoo! Network.

If you like to disable this setting, click the Opt-Out link and Yahoo! will immediately stop using Web Beacons to track your surfing habits on that computer. [via Anoop]

Trivia: A Web beacon can be detected by viewing the source code of a Web page and looking for any IMG tags that load from a different server than the rest of the site.
