FireFox "jump to URL" not working

Hello,

What I am trying to acomplish works in IE but not in FireFox, is there anyone who can help me out?

I launch the Articulate story from a landing page and at the end of the of the story I have a Button that should take the user to a URL for a survey. This process works like it should in IE but not in ForFox, it just closes the Articulate story and goes back to the landing page.

In Articulate I am using a Button Trigger "Jump to URL/File"

Any suggestion how to make this happen in FireFox?

Tom
