Rated 5 out of 5 stars

Useful: opens IE quickly from bookmark or already-loaded page. It's needed in particular since IE Tab does not work in Firefox 3.6 and Coral IE Tab did not work on my PC.
Since it's simple and light-weight, IE Viewer may actually have an advantage over in-tab IE viewers.
Thanks, Paul Roub!
