how to launch IE browser from firefox?

Hi,

I have one requirement that on clicking on a button from vaadin running in firefox, I want to open IE browser with a specific url. Is it possible in Vaadin?

Thanks,
Trivedi

Is it possible in vaadin? No
Is it possible from the web? No
Is it possible from firefox? Yes, with a add-on https://addons.mozilla.org/nl/firefox/addon/open-in-ie/

It it where possible, it would be a serious security flaw.
