It's a JQuery code that I'm using for GreaseMonkey. This is my script:
// ==UserScript==
// @name Delete test
// @namespace nope
// @description hi der
// @include *.*
// @version 1
// @require http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js
// @grant none
// JQUERY
[insert jquery.min.js here]
// JQUERY
var item = $(':contains(ANCHORFREE_VERSION=)');
$item.empty();
// ==/UserScript==
I have no idea why it's not working.
EDIT: I'm trying to remove all scripts that contain that text.
