At times, you would encounter sites that do not display well in Firefox, as they are predominantly designed to work only with Internet Explorer. The IE Tab 2 plugin allows you to view these pages in Firefox by using Internet Explorer to render them in Firefox. Classic examples where you could use this plugin is on sites that use Microsoft’s SharePoint Services. The plugin requires you to have Internet Explorer installed on your computer. Now, why the heck would you use Firefox, if you already have Internet Explorer installed? Perhaps, it’s a question of choice or preference. Internet Explorer 6 does not offer tabbed browsing, and Firefox does.
