This isn’t as good as Firefox or Brave, but it’s a step in the right direction. Max Willens on Safari’s updated private browsing mode:
Safari browser, which began rolling out to users in late September, prevents sites from detecting when Safari visitors have the browser’s private browsing mode enabled. Private browsing, like incognito mode, temporarily prevents publishers from reading or writing cookies to a phone or computer, which makes it impossible for a paywall to detect how much content a reader has consumed, thereby rendering the meter useless.
Why can’t browser makers set up simple toggle buttons for such features? Toggle on, toggle off? Instead, the features you need are buried deep in Settings or Preferences.
