Go to menu ≡ -> Settings -> General -> Applications. Do you have the "JNLP file" there? Check the action.

You can check the JNLP setting in the Advanced tab in the Java Control Center (JNLP File/MIME Association). In Firefos in handlers.json this JavaWebStart action would appear as something like this:

"application/x-java-jnlp-file":{"action":2,"ask":true,"handlers":[{"name":"javaws","path":"javaws"}]
