I would NEVER advise using M$IE
--much less reinstalling it once you're shed of it.
I assume you used Ieradicator.

Treating it like a version update from M$ should reinstall it.
I have found that whenever Mozilla chokes on a poorly-coded site,
my slimmer backup browser (Opera 6.0) will open it--no problem.
Opera is now freeware (the trialware ads are gone).
You seem to have a similar workaround.
If the content of a site is Windoze-centric,
before allowing the browser a chance to go there and crash,
I often feed the URL into the Validator.
As I said, most Windoze idiots use IE to "check" their HTML.
My instincts are rarely wrong on this.
When I do get crashed
and afterwards feed that site's URL into the Validator,
I don't think I need to tell you what I find.
BTW, even if some idiot PHB forces you to use ActiveX,
you can get an ActiveX plug-in for Seamonkey or Firefox.
It's been a long time since I've seen a valid reason to use IE.
