Hay una manera realmente fácil de moverse, incluida una copia completa de jQuery para los scripts de Chrome cuando esos scripts en realidad no usan ninguna característica privilegiada ( funciones GM_ *, etc.) ...
¡Simplemente inserta el script en la página DOM y ejecuta! La mejor parte es que esta técnica funciona igual de bien en Firefox + Greasemonkey, por lo que puede usar el mismo script para ambos:
var script = document.createElement("script");
script.type = "text/javascript";
script.textContent = "(" + threadComments.toString() + ")(jQuery)";
document.body.appendChild(script);
function threadComments($) {
