Thank you for the quick response.  I will run the connection in split
tunnel mode tomorrow and see how it goes.  I use the GUI in Ubuntu to
manage OpenConnect.  I assume I enable the split tunnel using the
following steps (please correct me if I am wrong):

Network Icon --> VPN Connections --> Configure VPN... --> Edit... -->
IPv4 Settings --> Routes... --> "Use this connection only for
resources on its network"

If that doesn't help, I will follow your next step of monitoring
Firefox configuration storage.  Thanks again for providing some
guidance with this issue even though it's technically is outside the
realm of your application.
