Chrome Dev Tools: How to trace network for a link that opens a new tab?

Check out chrome://net-internals/#events (or chrome://net-export in the latest version of Chrome) for a detailed overview of all network events happening in your browser.

Other possible solution, depending on your specific problem, may be to enable 'Preserve log' on the 'Network' tab:

and force all links to open in the same tab by executing the following code in the console:

[].forEach.call(document.querySelectorAll('a'),
    function(link){
        if(link.attributes.target) {
            link.attributes.target.value = '_self';
        }
    });

window.open = function(url) {
    location.href = url;
};

The feature request mentioned in the comment by phsource has been implemented.

In recent versions (starting with Chrome 50), you can go to the Developer Tools Settings menu (open Developer Tools, then use the 3-dots menu or hit F1) and check the box that says "Auto-open DevTools for popups".

In Chrome 61.0.3163.100 you now have the following option available. It is accessed by going to the Chrome Dev Tools Settings. It's at the bottom.

In Chrome 85 (still valid in Chrome 100) "Auto-open DevTools for popups" is hidden in a new place

DevTools (F12)/Settings (F1, Ctrl + ?)/Preferences/Global (at the end of the list)

And now it keeps the "Preserve log" setting.

You can do it this way :

set target="any_window_name" on wanted link. click on that link once, to open it in new tab. In opened tab, open developer tools. go back to origin page and hit that link again. The result will be loaded in already prepared window with developer tools opened. You can activate "preserve log" option in dev tools (see in Konrad Dzwinel excellent answer) to catch any redirect traffic on that link. Note : most people familiar with link target ∈ { _self,_blank,_parent,_top }. But actually any name can be given, this will open a new window with that name, and any subsequent clicks on links,forms or window.open with same target value will be opened in same window. further reading - mdn : window.open , mdn : tag

Works for me when I monitor Google Drive download responses

HttpWatch on Windows can record the network traffic generated when a new Chrome tab or window is opened by enabling auto-recording in Tools->Options->Recording. In the new window click on the HttpWatch icon to view the network trace.

The free version will provide basic information such as URL, status code and elapsed time for each request.
