Internet Explorer inside Firefox

Even the hardcore Firefox users need to use Internet Explorer once in a while. There are two reasons for that:

1. Sometimes you need to perform cross-browser testing to make sure that your website is being displayed correctly in both browsers

2. Certain sites, like the Microsoft Windows Update homepage, require the user to be using Internet Explorer

In order to avoid having to switch between browsers you can use a Firefox extension called IE View. The extension allow the user to load pages under Internet Explorer with a single right-click, and it also makes possible to make some sites load under IE by default.
