You're right, SpyDie, it is about our personal opinions & preferences. At least when comparing IE, Opera & Firefox, for me, its become more than a "security" issue.
Certainly, IE can be locked down. Being on dialup at home, I don't want to wait for the pages to load with IE. Opera is reportedly the fastest browser. I like Opera but have less control with it than with Firefox. Even at work (like now on much break), I still prefer Firefox, if for nothing else, for the BBCode extension. I like to use the Quick Reply so the BBCode extension makes it easy to select text and add the BBCode format (without having to stop & think about it). See, it really does come down to personal preferences.
