Okay, so getting a prompt before downloads helps.
You mean, the website automatically forces a download?
Or is it any download, like one you might want.

I believe it's an automatic, forced download (something like that, I'm not teckie enough to know the correct terms). Since IE doesn't ask for it to be checked by the user, it goes unnoticed. That's what FF checks and prompts you for.

Do you need some popup blocker or extension/plugin?

I dunno.


EDIT: Polo, this link ( http://www.skynet.ie/~caolan/publink/libwmf/libwmf/doc/ ) isn't really clear unless you understand that gibberish.
Anyways, as long as we get that it's automatic in IE, I think it's all that matters. Or not.
