Firefox called Microsoft out for moving Edge off Manifest V2, the extension system that lets uBlock Origin do its real job. Chrome already walked that road. Firefox’s line was basically: you can still just… use an ad blocker here.
Good. Switch if you have not.
A DNS that blocks ads, trackers, and phishing is the next layer, and most of the good ones are free: AdGuard, Control D, Mullvad Adblock, NextDNS, Quad9, dns0.eu, DNS4EU, CleanBrowsing, Cloudflare Families. Put one of those in the router and every device in the house stops phoning home quite so loudly.
Do it. Then understand the limit.
An ad blocker stops a tracker from loading in your browser this visit. It does not remove the profile a broker built from last year’s purchases. The eerily relevant ad you hate is often not a cookie. It is a match of your email to a file that already had your house.
So: Firefox + a blocking DNS + deletions to the brokers. That is a stack. A new browser alone is a mood.
