Editing HTTP Request Headers and Body using a Browser

In-order to edit the headers and body of a HTTP request, we need to use Mozilla Firefox. Chrome doesn’t provide any built in tools that allow editing the HTTP request. Firefox provides a built-in functionality inside the developer tools to do the task.

Open the developer tools of Firefox (Ctrl+Shift+i) and select the network tabs. Then open the website and select the particular request to be edited.

Select the edit and resend option from the headers tab.

Now you can edit the parameters and resend the request.
