Using Firefox version 102: Open '''console tools''' and navigate to '''Network''' tab Right click on a '''POST''' request '''"Edit and Resend" is no longer an option?''' There is still the '''resend''' option Clicking resend allows you to edit the request, but unfortunately the "Content-Length" attribute is not automatically updated like it was with edit and resend, so all requests fail after being edited. This is because the Content-Length header indicates the size of the message body, in bytes, sent to the recipient. When you add or removes bytes in a JSON request for example, it doesn't get updated. The attribute can also not be manually set. How can I use version 102 to edit and resend requests the same way I used to? Thank you.
