what is curl browser
1 Answer 1. cURL is not part of Firefox or Firebug, i.e. it cannot be executed there. cURL is a command line tool for transferring data with URL syntax. Firebug's Copy As cURL command recreates the HTTP request (including HTTP headers and query string parameters) and copies it as a cURL command string to the clipboard. The string can be pasted into a terminal window to execute the same request or for example pasted to a client that supports cURL.
