I am trying to work at home through Citrix for my new job. I downloaded Citrix and am able to access my home screen with all of my work program icons. When I try to open a program, I get a message that says "You have chosen to open launch.ica which is ica file 1.5 from citrix. What should Firefox to with this file? Open with ??? or Save." I want to open it but don't know what to chose so Firefox can open the file. What do I choose?
