Yes DavidR,
Some of these critical flaws have been fixed in FF. If IE were so quick as to fix theirs, there would not have been FF. A lot of FF's vulnerabilities still only work through an unpatched IE browser on the system. What was wrong with IE is building a browser as a conclusive part of your OS, very very unsafe policy. Active X was another of these examples, where the whole comp is open to attackers. FF has their holes as well, even in the last version. They work on that. But I know all over the net anti-spyware, and adware experts advice FF, and not only because of their big blue Mozilla eyes,
