[Project_owners] privileged and unprivileged javascript prototypes

Thanks, Neil. I'd like to execute this code for every window, then.
So what I tried was:

In XUL overlay:
  window.addEventListener("load", function() {myext.init();}, false);

In myext.js:

  var myext = {

    init : function() {
        .addEventListener("load", this.pageLoad, true);

    pageLoad : function() {
      String.prototype.foo = "foo";

Yet this attribute/property still doesn't seem available in HTML
pages. I suspect I must somehow get the Window object in pageLoad()
and call String.prototype.foo on that. Is that correct?

Thank you very much,
Eric Jung
