Steve, that is a catch-22 - it requires that I install a google add-in to my browser in order to opt out of having information about me shared with google, which is totally unacceptable to me because it requires that I permit google a certain amount of access to my internet activity in order to get and use their app.
Oh, by the way, there is also a notice on the page linked from that paragraph that says:
The Google Analytics Opt-out Browser Add-on is not supported for your browser.
In the text on that page, it says:
The Google Analytics opt-out add-on is designed to be compatible with Chrome, Internet Explorer 11, Safari, Firefox and Opera. In order to function, the opt-out add-on must be able to load and execute properly on your browser. For Internet Explorer, 3rd-party cookies must be enabled.
Steve, I appreciate your efforts and don't want to shoot the messenger but ... sorry, this is not what I consider an acceptable answer.
