The Security Mentor

That headline asks a meaningless question. If you ask a question about Firefox versus Internet Explorer (the "blue E") and if the question is specific enough to answer, you can get any answer you want just by changing how you ask the question (but I still recommend Firefox!).

It's only one of the questions you could ask, but "which of the two fixes security bugs faster?" is a useful question. It doesn't tell you which browser is "more secure" but it's a good thing to think about.

The Firefox team fixes security vulnerabilities six times faster than Microsoft does, according to Brian Krebs at the Washington Post.
