A problem which I never expected a solution seem to have been addressed.

Problem:
I use Firefox 3 for almost all purposes. But there are some sites, specially windows update, internal corporate pages, Microsoft Sharepoint for which I need to switch to IE. That was kind of an irritating thing.

Solution:
Firefox Plugin called IE Tab opens up IE inside your Firefox window. You can configure which sites should be automatically be opened using IE.

This is the coolest thing that has happened to me today -- finding IE Tab.
