Is there a Firefox Tab like IE Tab?

Question

IE Tab allows users to view pages using the IE rendering engine. Is there something along these lines the other way around, rendering a tab using Gecko in IE?

Is it possible to write an ActiveX control to include the Gecko engine or webkit and use that to render the page?

Answer 1

You could write an ActiveX control to do this. However, I suspect it would be much harder to host Gecko in IE than to host IE in Firefox.

Answer 2

I don't know if it's true, but IE 8 seems to have some similar feature:
