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?
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.
