I'm developing in Firefox and was asked today to test connectivity drops. How do I simulate this from the developer tools? All I can see in the network tab is speed throttling, ranging from GPRS to WiFi. How do I disable the internet entirely?
(I can't just turn the laptop's Wi-Fi off, I want the DB GUI up in a separate window.)
I noticed that accoring to this answer, Chrome has this feature, but I don't use Chrome.
