Esiste un modo davvero semplice per spostarsi, inclusa una copia completa degli script jQuery per Chrome quando quegli script in realtà non utilizzano alcuna funzione privilegiata ( funzioni GM_ *, ecc.) ...
Basta inserire lo script stesso nella pagina DOM ed eseguire! La parte migliore è che questa tecnica funziona altrettanto bene su Firefox + Greasemonkey, quindi puoi usare lo stesso script per entrambi:
var script = document.createElement("script");
script.type = "text/javascript";
script.textContent = "(" + threadComments.toString() + ")(jQuery)";
document.body.appendChild(script);
function threadComments($) {
