IE Tab allows Win Firefox to display IE-rendered pages
The world rejoices as an extension, IE Tab, has been released that allows users to view content in either the Gecko or Internet Explorer engine. This functionality has been a part of Netscape 8 for some time, so it's not ground-breaking, but still, I will be forced to open Internet Explorer up much less often! Windows Update even runs properly in Firefox via this extension. How cool is that?
It adds a contextual menu item so you can right click a link to open up a new tab of IE-rendered content. It also adds a browser icon to the status bar, so the little Firefox icon in the status bar can be clicked, which reloads the page in IE mode and switches the icon to the blue E. You'll always know which engine you're viewing in. Unfortunately this only works for windows since it uses the native IE engine.
