METODO DE CARREGAMENTO DO JQUERY (metodo_JQ):
1 = usar o @require do greasemonkey
2 = carregar o script de jquery.com e inserir na pagina
Tente usar primeiro o metodo padrao (1) que e mais rapido
Caso o script nao funcione, altere para (2)
Se ainda assim nao funcionar, informe na pagina do script em userscripts.org
