Open Firefox network developer tools when opening a page

The Network tab in the Developer Tools can be activated only when a page is already open. We have an application that opens a document in a new window. I can enable network logging on the main page, but when I click to open the document nothing is displayed. To see the very start of the log for the document page, I'm too late, the Network tab is empty. I can reload the page, but that wouldn't be the real situation.

My questions: Is there an option to activate the Network log right from the start of a page? -or- Is there a way to have ONE big Network log, with all pages combined??

Thank you for an excellent browser!

You can try to use the Browser Console and only enable XHR and Requests.

I did check the Browser Console and I did not see those options in the top-right corner. Awesome! Thanks a lot!
