I'm using Firefox in Ubuntu 22.04 LTS (snap version, so it's updated regularly) and I've been having this issue for months. I use Network pane heavily as aid to develop the backend portion of a web site with a JSON based API. Now and then I need to repeat an HTTP request, so I use the "Resend" option, and everything's fine except I'm unable to see the server response. "Size" column shows "0 B" and "Response" tab is empty. I'm positively sure the server cannot distinguish whether it's a brand new or resent request and does not send empty responses. It's something specific to XHR requests, regular requests are not affected. Troubleshoot Mode doesn't make any difference.

Is this a known issue or something that only happens to me?
