injected_javascript=("Object.defineProperty(navigator, 'webdriver', { value: 'false' })")
driver = webdriver.Firefox(executable_path=r'/home/kkkk/ggecko/geckodriver', firefox_binary=firefox_binary)
driver.get('https://auth.citromail.hu/regisztracio/')

// overwrite the `languages` property to use a custom getter
const setProperty = () => {
    Object.defineProperty(navigator, "languages", {
        get: function() {
            return ["en-US", "en", "es"];
        }
    });

    // Overwrite the `plugins` property to use a custom getter.
    Object.defineProperty(navigator, 'plugins', {
        get: () => [1, 2, 3, 4, 5],
    });

    // Pass the Webdriver test
    Object.defineProperty(navigator, 'webdriver', {
      get: () => false,
    });
    callback();
};
setProperty();
