This sort of works. Clicking inside the iframe doesn't trigger the events, but
clicking on the small grey border around the iframe first triggers the blur
event, and then triggers the focus event. Clicking somewhere else triggers only
the blur event.
I am developing an app where I have some elements of a form inside iframes, so
that they are reloaded when something else changes in the form. Problem is that
iframes participate in the "Tab-cycles-input-elements-of-forms". To solve this I
have an onfocus event on the iframe which when triggered puts the focus on the
first item inside the iframe. This works with IE, but not with Mozilla.
As mentioned in comment #4, clicking on the border surrounding an iframe will
trigger onfocus event handler. Also, if you give a padding to iframe, you'll
easily see that clicking in that padding area triggers the iframe's onfocus
event handler. Though the onfocus event for iframe will not be fired when
tabbing or shift-tabbing to it.

"This [onfocus] attribute may be used with the following elements: A, AREA,
So, Mozilla does not have to support onfocus for iframe, even though it kinda
supports it, at least internally.
Same thing with Opera 7.x's "Show Active frame border setting
(Preferences.../Page Style): When you view framed pages, the currently active
frame will always be outlined."

I agree that W3C recomendation to event focus in HTML documents may be used with the following elements: A, AREA, LABEL, INPUT, SELECT, TEXTAREA, and BUTTON, but the same example "Main document of test page" works fine in IE. Doesn't necessary to expand the padding and click it to the iframe has focus.
Are there any idea to fix it and works fine in FF.
