A robot told me: The Meta/Yandex exploit worked by having JavaScript running on a website (such as Meta Pixel) connect from the browser to a native app on the same device via the localhost (127.0.0.1) interface, using HTTP, WebSocket, or WebRTC. This communication occurs entirely within the device and does not traverse the network in a way that browser extensions like uBlock Origin can intercept or block. Browser extensions generally cannot block or even see requests made to localhost sockets, especially when those requests are initiated by scripts running in the browser and targeting native apps on the same device
