Prevent execution of a specific inline script tag

Delete script tag on document-start (as suggested by wOxxOm):

(function() {
    'use strict';
    window.stop();
    const xhr = new XMLHttpRequest();
    xhr.open('GET', window.location.href);
    xhr.onload = () => {
        var html = xhr.responseText
        .replace(/<script\b[\s\S]*?<\/script>/g, s => {
            // check if script tag should be replaced/deleted
            if (s.includes('window.location')) {
                return '';
            } else {
                return s;
            }
        });
        document.open();
        document.write(html);
        document.close();
    };
    xhr.send();
})();
