Yahoo Web Beacons "super tracking cookies" - How to Opt-out

Below is a recent discovery that can further improve your Internet privacy if you use Yahoo's free email services.

LINKS on how web beacons work

Yahoo is using something called "Web beacons" or a "super cookie" that tracks not only where its users go on the Yahoo network but also tracks where they go outside of the Yahoo network using a persistent file on the hard drive.  Note that you have to have a Yahoo account to be tracked. If you want to opt-out of this tracking, log in to your Yahoo account, then go to privacy yahoo.com/privacy.


1. Make sure you are signed on to your Yahoo account.

2. Go to this site to start this process


3. Find the "Cookies" Information section on Yahoo's Privacy Page and then locate this specific bullet point that discusses web beacons:

* Yahoo! uses web beacons to access Yahoo! cookies inside and outside our network of web sites and in connection with Yahoo! products and services.

4. Click on the web beacons link (as noted in bold above):

5. On the web beacons information page, find this paragraph:

When conducting research Yahoo!'s practice is to require our partners to disclose the presence of these web beacons on their pages in their privacy policies and state what choices are available to users regarding the collection and use of this information. You may choose to opt-out of Yahoo! using this information for this research. Please click here to opt-out.

6. Click on the Opt-out link (as noted in bold above)

7. After clicking on the link, you are done. You'll see the following to opt-out message.

You have opted out successfully. If you would like to cancel your opt-out request, you may do so by clicking the button below

8. Please do not click on the button shown on this page or you'll opt back into using web beacons.

9. I would then suggest deleting all cookies, or at least signing off and signing back on again with your Yahoo email account. If you use multiple browsers, clear the cookies out in each one.

10. If you have more than one Yahoo account, repeat this process for each specific account.
