You never mentioned what add-ons you've installed into IE and

Firefox in its safe mode?

I looked and they are all pretty much disabled anyway (shockwave,
silverlight, Java development Acrobat etc).

Disabling an add-on does not remove its settings (that you can see in
about:config). While safe mode is a troubleshooting step by disabling
all the add-ons, that doesn't change back to default any settings that
were changed by the add-ons. That's why the next suggestion is to to
create a new profile and load that (make it the default) when you load
Firefox.

Sometimes uninstalling the add-ons will remove their settings but not
always. I've found lingering settings from add-ons that were
uninstalled long ago when I happened to do some cleanup in about:config.
Since all those add-ons are disabled, you aren't using them, so why not
uninstall them. If that still doesn't help, try using a new profile.
