Some feedback: I was very enthusiastic about the Private Network feature until I noticed a problem: it bypasses all of the blocking in my /etc/hosts file (tens of thousands of hosts). Suddenly more websites are able to track and fingerprint the browser. As soon as I turn off the private network, the trackers are blocked again.
I would definitely pay for a feature like that, but not if I can’t block a custom list of tens of thousands of hosts where I’m sure that the requests to those domains are never leaving my computer. I hope that there is a way to fix the problem.
