It's performed in the background page context.

1. open chrome://extensions page
   (or right-click the extension icon in the browser toolbar, then click "Manage extensions")
2. enable developer mode slider/checkbox
3. click background in Tampermonkey's entry.
   (sometimes you'll need to open details first - in case several pages are shown in the card).

There is not developer mode slider/checkbox

Do I have to use Chromium instead of Chrome?

[volkirik]

They have made userscripts appear at developer tools in version 4.5 (2017-12-30).

I was hoping to see similar change for GM_xmlhttpRequest

Well, Google's designs were always bad, I know, but you can easily find a video or a tutorial that illustrates the procedure. I can show a screenshot:

They have made userscripts appear at developer tools in version

Userscripts runs inside the web page but GM_XHR runs inside a different page - the extension's background page, which is why it cannot be shown in web page's devtools.

Thanks so much. Life saver!
