jQuery $.getScript() usage with feedback widget rewrites entire page with feedback widget.
This is to avoid the document.write() call because that causes speculative parsing failures in Firefox 11.
This is exceedingly easy to reproduce. Either loading on dom content ready, page load event, or executing it immediately will overwrite the entire document.
I have serious reservations with using the should-be-deprecated document.write() function. Triggering speculative parsing failures in Firefox is unacceptable behavior for 3rd party libraries.
