Via Joel Spolsky, I ran across the coolest Firefox extension:

IETab takes advantage of the fact that Internet Explorer is available as an ActiveX control, which is available to be embedded in any Windows application, to open certain websites in Firefox using Internet Explorer. Whenever a website comes up complaining that you need to get "Netscape 4.0 or some other modern browser" you can just right click on the tab and it'll pop up right in Firefox being rendered by Internet Explorer. You can set up a list of websites that always come up in IE tabs

There are screenshots of the settings screen over at Joel's; you can list websites that will always use the IE control. This lets you route around the damage of people who think that IE specific websites are ok (like, for instance, the folks here at Cincom who maintain the internal websites. Sigh). Runs in its own tab, which is very nice.
