Unable to capture traffic from Chrome incognito window only

I want to capture traffic from a Chrome Incognito window only.

When I click the 'pick target' button on the toolbar and point it at the Chrome window it picks up some particular process from chrome, but that does not seem to be the one from where network requests are sent from.

Looking at Chrome's Task Manager and comparing with what Fiddler shows, Fiddler is picking up the "Browser" process, while requests are coming from the "Utility: Network Service" process, thus the difference.

An acceptable solution for this would be if we could enter the process ID manually in the UI, instead of using the target picker.

Hello all,

I am declining this as duplicate of "Target Any Process" feature no longer working with Chrome.

In terms of a fix, it probably makes sense to special case Chromium-based browsers such that if the user selects a Chromium process (chrome.exe, brave.exe, msedge.exe, opera.exe, etc) then the tool looks for the network service utility process owned by that UI process. This should be reasonably straightforward.

An alternative approach is to untick File > Capture Traffic, then start Chrome thusly:

   chrome --incognito --proxy-server=http://localhost:8888

The Incognito window will direct its traffic to Fiddler.

This is

If your goal is to filter to a single process ID, you can use FiddlerScript or the dropdown on the Client Process pane of the Filters tab.
