Does Firefox have a spyware problem?

There is some debate as to whether or not Firefox is a threat to a computer by allowing spyware to infect any IE program on a computer system. If you use Firefox and click on a suspicious link, you could download malicious software. For some, like the author of the link below, that is a problem because they believe that Firefox should protect users from all problems [even chosing to click on dangerous links]

Others, like the writer of the link below argue that Firefox can't be held responsible for the foolish actions of others - especially if it warns people not to click on these links. I think the issue is whether or not a program causes problems if used as it is intended to be used, not if it causes problems if it is not used as intended.
