I'm loading a page into a <browser type="content"> but I want the close()

Uh, I hope you meant:

(ie, no braces after close[()])
But *if* you're managing to touch the underlying object, that's a
security issue waiting to happen, AIUI (what if content defines a setter
function on the window's "close" property?). CC'ing bholley who gave a
talk[0] about this stuff and knows more about this (and might have
solutions and/or assuage my fears as to the security of this).
