Partial answer:
If someone said this, sorry. (I looked ahead, but am trying to catch up...)
You can "elect" to stop USING IE,
but you can't stop things that are "hard coded" to use it - from using it.
Since it is "built-in" to the OS, you MUST keep it patched,
if you are using it or NOT.
All this sneaky stuff that runs around trying to invade our systems will
not care if you run FF or not. As a matter of "fact", it will "love it"
if you neglect IE patches at the same time....

I am ready to give IE the boot! IE is driving me over the edge, finally.
Most likely, because I refuse to keep up with all the internal bits/bytes
that M$ changes to "improve" their product.
