Another Serious Internet Explorer Issue?

I recently received an email from someone alerting me to an exploit that’s infecting a variety of established websites. This story, illustrates the importance of having your computer protected with good anti-virus and spyware software if you’re going to be browsing around the Internet trying to uncover that latest cool tidbit of bits and bytes. This video and report highlights Symantec’s Norton response to the exploit.

However, what the story didn’t make clear to me was that if this problem impacts only IE browsers or anyone surfing to the site from Firefox as well.
