When you sent data over a form, you can see what exactly you sent if you see the logs on the Firebug console. It also gives you an option to resend the data. Is there is a way to edit that data within Firebug to send something different? If not, I would like to know if there is any other tool that can.
This is an example of what I see on Firebug console after having sent a certain form:
Params Headers Post Response JSON
Parameters application/x-www-form-urlencoded Do not sort
[action]
save
[user name]
Someuser
[Source]
action=save&username=Someuser

There is no such option in Firebug, but the Firefox built-in DevTools allow you to edit the data of a previous request and send it again.
To get there, first select the Network panel, then in there a request. When you click on the Edit and Resend button, you'll be able to edit everything, the request method, the URL, the query string, the headers and the body.
After a click on Send the request is sent to the server.
