This guide shows how to install three different Internet Explorer versions (6.0, 5.5, and 5.0) on Ubuntu Feisty Fawn, Edgy Eft and Dapper Drake desktops. This is good for people such as web designers who have switched to Linux but still need to test their web sites in Internet Explorer. In addition to that, there are still a few web sites out there that work only in Internet Explorer.

Es4Linux is the simpler way to have Microsoft Internet Explorer running on Linux (or any OS running Wine).
