A way to increase browsing privacy is by using DoH. Unfortunately most ISPs do not allow on their DNS (Domain Name Servers) which, pretty much, makes setting it up useless but no one demands that you the ISP DNS. Personally I have used OpenDNS for more years than I can remember. I set, both, my browsers and router to use OpenDNS.
