To provide website visitors with more choice about how their data is collected by Google Analytics, google has launched a new add-on called “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 Internet Explorer (versions 7 & 8 and also may work on IE 9), Google Chrome (4.x and higher), and Mozilla Firefox (3.5 and higher).
