How do I deactivate the internet entirely with Firefox's developer tools?

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.

Solution

  • This is not available in Firefox devtools. You can follow this bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1029203

    In the meantime, you can use "Work Offline" in the File menu. On Windows, press Alt to show the menu bar: https://support.mozilla.org/en-US/kb/restore-menu-bar-firefox#firefox:win11:fx108
