It seems that both our Non-Volatile and Volatile Zen 10.3.1 policies do not persist the install of flash within Firefox.

When I log on as the local administrator account flash works for both IE and Firefox, but with any users that receive a DLU it must be reinstalled upon each logon within Firefox.

Is there a Group Policy setting that could be dictating this behavior? I find it strange I see this happening even with my Non-Volatile users where the profile remains on the computer.
