Debugging Mode

https://chromedevtools.github.io/devtools-protocol/

chrome.exe --remote-debugging-port=9222

You can then see:

Then you can start a separate client Chrome instance, using a distinct user profile:

chrome.exe --user-data-dir=<some directory>

Now you can navigate to the given port from your client and attach to any of the discovered tabs for debugging: http://localhost:9222
