Connecting with Firefox 30

There is a known Citrix issue with Firefox version 30. Released June 10th, 2014, this version of Firefox includes a security feature that prevents the Citrix Receiver plugin from being activated unless additional action is taken.  There are currently three workarounds for the problem. If you have questions or if these workarounds do not resolve the problem, please email app-virt-support@rt.andrew.cmu.edu.

Workaround Solutions
