google analytics opt out tool

Hi All,

I have enabled my privacy opt outs religiously, but one website (my church!) provides none; they suggest google analytics opt out. So I downloaded and installed it as an extension in my applications folder.

Is this tool worthwhile? It states upfront that it permits web pages and personal information to be viewed. That doesn't sound good. What's the verdict on this tool? Especially for Safari?

Finally, how do I know it's enabled and working--is there an icon on my menu bar or something? Or is there any report about what site analytics have been blocked?

Thank you.
