Granted this is no shock headline but there are figures backing up the claims. The Browser Vulnerability Analysis report (in PDF format) written by Jeff Jones, Security Strategy Director records that since November 2004 there have been 75 critical vulnerabilities in Firefox but just 54 for Internet Explorer in the same period.

These figures certainly go against the popular opinion about the two browsers but no one can deny the efforts made in IE7. As frustrating as the various Info Bar confirmations can be, they do mean that there is a higher chance of stopping attacks.

One thing that would interest me greatly about the relative security of these two browsers is the implications of addons. I think people are even more trusting about addons than they are about other software on the internet. Although I've found addons really useful for both browsers, I do worry about them posing a security risk.
