Firefox + uBlock Origin + arkenfox user.js gives you privacy, security and anti-tracking. The only way to fly IMO.
White list firewall. Because this is the real reason everyone has a right to ad block. Ads are hidden links to other websites. It’s like walking through a gauntlet of pick pockets bribing the credit card company just to make it to the checkout at your local grocery store, or some asshole you invite into your home that goes to the bathroom, opens a window, and lets a dozen random people in your home if they pay a dollar for the access. The entire system is based on stalking people. It is criminal.
A dns blocker cannot do anything more than ublock. It is nice for other apps though.
