Block Google Analytics cookies
Feature added: November 28, 2005
Google Analytics (also known as Urchin) is a service from Google that helps website owners analyze how users use their sites. Information about your use of a certain website (including your IP address) can automatically be transmitted to and stored by Google using cookies.
Today, more that 200,000 websites use Google Analytics. You might have visited such a website without knowing about it. You can always check the source code of a page to find out if they are using Google Analytics.
Google Analytics tracking code
If you're concerned about your privacy, you might be wondering what you can do to opt-out from Google Analytics. Today, there's no easy way of doing that.
CustomizeGoogle has a new optional feature that blocks all Google Analytics cookies, on any website. You can find this feature in
Firefox -> Tools -> CustomizeGoogle Options... -> Privacy
Using this feature makes you more anonymous. But your visit on a single webpage can still be logged. This way, both Google and the owner of the website knows that someone visited a webpage, but it's difficult to track all pages you're visiting. And it's really really hard for Google to track that you visited both Website A and Website B.
Note: It's not impossible to log your visit, since your ip address is still sent to both the website and Google Analytics. Also, the website might be using Google AdSense which uses a separate cookie.
