Firefox - How to view network request that opens new window


I am trying to debug (someone else's) site where there is a button that opens a new browser window that leads to a 404. I am trying to determine if the new window is opened with a POST, but the old window's dev network tools don't show the request since it occurs in a new window. And when I open the dev tools in the new window, the request has already been made and doesn't show up.

How do I view this network request in the dev tools?


Solution

  • You can open the Browser Console, beware it's not the same as the Web Console.
    From there, you'll be able to monitor all Requests made from all contexts, by switching-on the "Requests" toggle.
