Greasemonkey XHR not showing in firefox network devtools

Question

I wrote a script as a user script and ran it on a specific website with Greasemonkey.

It worked perfectly, but I want to see requests that my script has sent in the Firefox developer tools network tab. Currently it shows the page's requests and not my script's requests.

What should I do?

I suspect that FF 57 does not have this capability; they broke so much... You can try debugging your script on a Chromium based browser (and Tampermonkey). — Brock Adams, Dec 10 '17 at 06:38
@brock-adams Thanks, is it possible to send requests with XMLHttpRequest ,like original page requests ? to show requests in developer tools? — odr_m9611, Dec 10 '17 at 07:05
It's possible in Chrome, but was always tricky in FF. With FF 57, I'm not even going to check. — Brock Adams, Dec 10 '17 at 07:29
Ok, I inject the user script to the main page (with Greasemonkey), and now shows the user script requests in the Developer tools like page originally requests,Thanks — odr_m9611, Dec 10 '17 at 07:35
Yes, but you won't be able to do cross-domain xhr, nor use GM functions that way. But I guess you don't need such (yet). — Brock Adams, Dec 10 '17 at 08:10

You need to open Browser Toolbox to see XMLHttpRequest of Greasemonkey.

See how to enable and open Browser Toolbox.

(Check "Enable browser chrome and add-on debugging toolboxes" and "Enable remote debugging" in Developer Tools Settings)

You can find any XMLHttpRequest in the network monitor under Browser Toolbox.
