Network Tab: how does "Modify and Resend" feature work?

(Kantoche) #1


I’m using FF 63.0 (Mac) and I would use the “Modify and Resend” feature to test an URL.
When I click on the button “Modify and Resend” the panel associated to the URL is closed, and no editor appears to modify the request. So, how to use this feature? Thanks.
