Comment 3 for bug 1588847

... On IceWM:
              -we've got a toolbar entry for firefox, since firefox is also installed an the client image, we naturally want to run it with ltsp_localapps
              -when an ltsp client connects, $LTSP_CLIENT is set, so on ltsp_localapps runs normally
              -when an x2go client connects, $LTSP_CLIENT is unset, so on ltsp_localapps executes the command (firefox) on the server and logically firefox is run for the connected x2go client
