Block Third Party & Advertiser Cookies Easily in Safari
Starting with Safari 5.1 in OS X Lion, you can now selectively block third party and advertiser tracking cookies easily within Safaris’ preferences. There are some reports that blocking the third party cookie option is the new default setting in Safari 5.1, but if you want to adjust this yourself here’s how:
- Pull down the “Safari” menu and select “Preferences”
- Click on the “Privacy” tab and select the ‘third party and advertisers’ radio box alongside the “Block Cookies” option
Blocking these cookies is different than using a browser ad blocker plugin because it simply forces the ad cookies to not gather data rather than blocking the ad completely. Third party ad cookies are generally used to serve relevant ads to web users, this is achieved by monitoring web usage habits and then serving ads based on the sites you visit. For example, if you visit a lot of Apple-related sites, you’ll probably see Apple-related ads elsewhere on the web. You can read more about this practice on Wikipedia.
