I'm still learning and catch will correct me where I'm wrong. (from the Brett D. Fleisch publication) If I'm correct this stems from the TOS layered design and ring structure(one type of design): level zero being your innermost core and most secure, and the outermost layer being level eight (untrusted user programs) being least secure. So, with firefox you're getting further away from your security core, and IE is protected by inner layers or rings closer to its core, figuratively speaking? I guess until TOS philosophy is widely adopted and the ideals are applied to lower level systems; like security mechanism education and the likes. I'm afraid we'll continue to see old habits dying hard and more prosy threads like "my system is broke" etc... With an acronym such as the aforementioned, it’s blatantly obvious that we're dealing with deep security, as deep as you can go, you'd think it would be welcomed on a site with the slogan of this one. Sadly, it's eschewed for reasons of silly pride or whatnot or lack of understanding and comprehension .

I wish not to be like all those other poor dullards and choose to think out of the norm.
