Hope I am posting in the correct forum. I am trying to figure out how to block 3 party trackers (the kind that track unique visitors/audience etc) but keep some (such as Google Analytics) for a client. I have figured out Alexa and Website Outlook.

Any advice would be appreciated.

I would recommend you to use NoScript add-on with Firefox. Thus, you would have full control on which tracker to use or not.

Wish this help,
