I need a way to have the developer tools open when a new window opens.

[이희구]

When a new window is opened, the developer tools opened on the original page cannot view the network information of the new window.

I would like to have the developer tools open automatically when I click on a link that opens in a new window like Chrome, so that I can see the initial network information that is generated.

This has been requested before and here is a bug in our tracker:

Perhaps using Multiprocess Browser Toolbox (MBT) can help you

You can use the MBT in multiprocess mode to capture requests for new windows.
