Generally speaking I'm with you on the whole Firefox advocacy front, but really it is a poor idea to convey the message that Ff is impenetrable. The facts tell us that Ff is more secure, and that's probably because it is, but it's also most likely related to the fact people do not aim to attack Ff as much as they do IE.

The popularity of Ff vs IE is sometimes exaggerated. Around 85% of Internet users still use IE. Therefore, it makes sense that the exploiters aim at that browser.

That said, Microsoft have been lacking in the security department for some time and they quite obviously realise that this is a serious issue which is affecting them. About time. Looking at the next version of IE it would seem they are going to be putting a lot of resources into securing it, which I think (justified or not) is going to save them from the Mozilla threat. What a sham(e) that it's going to require Vista!

I've been using Ff since 8.0 and I like it. I refuse to be caught up in the browser wars, I'll use IE for Windows Update and viewing ActiveX sites, otherwise I'll use Ff. Nothing MS or Moz pulls out of a hat is going to make me keep switching default browsers for their sakes.

If you're Internet savvy enough, either browser is secure enough to use without getting your computer infected. Some of the responsibility should lie with the owners of computers don't forget. They need to stop being so thick and downloading files such as 'freeporn.exe' (though obviously in the example you link to, it is just MS's responsibility and typically slow response).
