Comment 8 for bug 345777

i opened the home page inside the "Developer Tools" thingie that IE 8 has and found that the button is in the DOM tree as:
<input id="help-close-btn" type="button" value="Continue">
under the "invisible", "help-footer" and "help-close" blocks.

for details, i'm attaching a screen-shot (couldn't find out how to copy as text from their interface...).
