At work when trying to identify really slow APIs (5+min), I used to (version 52) be able to click on the request and see the request headers, params, url, etc. We have recently upgraded to version 55 and now the headers tab in the network monitor says "No headers for this request" until the call is finished. Then it shows the response headers, request headers, the request url, etc. Is there a way to see the request url, method, request headers, request params, etc before the call completes like in previous versions of firefox?
