Google Analytics Opt-out Browser Add-on (BETA)
To provide website visitors more choice on how their data is collected by Google Analytics, we have developed the Google Analytics Opt-out Browser Add-on. The add-on communicates with the Google Analytics JavaScript (ga.js) to indicate that information about the website visit should not be sent to Google Analytics.
If you want to opt-out, download and install the add-on for your current web browser. The Google Analytics Opt-out Browser Add-on is available for Microsoft Internet Explorer, Google Chrome, Mozilla Firefox, Apple Safari and Opera.
There is also a separate plug-in to opt-out from their personalized ads.
