I have firefox as my default browser on a Mac book Pro. I am trying to log into my company remotely for the fist time on the Mac. (my netbook connects fine but is running Microsoft IE for the browser)

When I go to log in and choose to connect to my workstation a pop up states that i need active x controls and my security settings may be blocking and to make changes to these settings and try again. I cannot seem to find where to make these changes.
