Same account, same Safari tab, minus the scroll trap. ZERO FLASH Curb loads blocking rules before the page paints, so the feed never appears, not even for a split second. A SIMPLE GUIDE Where the feed was, Curb can show a short on-page guide pointing you to what still works on that site. Toggle it per site in the Safari toolbar popup. YOU STAY IN CONTROL One switch per site. Turn any platform on or off anytime from Safari’s toolbar, no digging through settings. PRIVATE BY DESIGN No accounts. No servers. No analytics. No tracking.
