I assume you mean from an extension and not on your project page :)
If so, then wait for the page to load, get the document content, and:

var s = document.createElement("script"); 
s.setAttribute("type", "text/javascript");
s.appendChild(document.createTextNode("alert('hello world');"));
document.getElementsByTagName["head"][0].appendChild(s); // won't work if document has no HEAD
