i do something like this on firefox and the container tabs feature.
i create a set of container tabs for websites that do tracking with cookies and only visit that website using its dedicated container so that it looks like i ONLY use my browser to go to ONLY go to that one website from the trackers perspective.
i also started using privacy badger and ghostery to give the tracker junk information to make all the data harvesting useless; but i don’t know if it works yet.
how could you tell it was a 10/100… or even a cisco switch?
it looks more like an old small plane dell powerconnect to me.
