Joe maybe I'm PM you to describe the goal if needed,(offline) but in short, can I just ask your opinion on this specific question:

If I'm in private browser mode, firefox, safari, or Chrome, and I search in Google soemthing, and I do this at various locations, with different IPs, will Google (as an example with their vast echnology), recognize it's the same laptop, or ihpone doing the searches even though I'm in private mode and different ips?? I understand that private mode deletes the cache, but others say now they still may know its the same computer because of a "digital fingerprint"

or is this BS?
