Basically title. Recently I saw a new option in Chromium website permission settings called “allow access to local network” or something like that and I know some antiviruses on Windows that can list all devices connected to the same WiFi network. I’m usually using Firefox based browsers that obviously don’t have the option to disable or enable that access. So can some really invasive websites mine data about my local network, connected devices etc? And if so, what can I do to prevent it except for just disconnecting everything else when visiting such websites?
