Bug 263931

1. Go to http://example.org/
2. Open Web Inspector
3. Open Network Tab
4. Copy HTTP Request
5. Copy HTTP Response

This gives the following results:

HTTP Request

So far so good.
Let's do the same thing on https://apple.com/ which is HTTP/2


HTTP Request

:method: GET
:scheme: https
:authority: www.apple.com
:path: /
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Sec-Fetch-Site: none
Cookie: ****
Accept-Encoding: gzip, deflate, br
Sec-Fetch-Mode: navigate

Accept-Language: en-US,en;q=0.9
Sec-Fetch-Dest: document
Connection: keep-alive


and the HTTP Response:

:status: 200
Content-Type: text/html; charset=utf-8
Vary: Accept-Encoding
Content-Security-Policy: *******
X-XSS-Protection: 1; mode=block

It would probably be better for consistency to display it as
