In a html file of the local pc directory, I want to execute grease monkey. I was not able to execute the following file.
// ==UserScript==
// @name test
// @namespace aaa
// @include file:///C:/fx/test/a.html
// @version 1
// @grant none
// ==/UserScript==
alert('c');
What should I do to execute grease monkey in local html file.
