It seems that firefox 68.x, as distributed with CentOS6 updates, no longer allows opening jnlp files with javaws

The "Choose Helper Application" window popping up after selecting "Open with/Other" has a predefined list of applications that cannot be customised.

I'm sure it must be a configuration issue as this works fine with the same browser on other distributions, but what to look for?

# alternatives --display javaws          
javaws - status is auto.
 link currently points to /usr/java/latest/jre/bin/javaws
/usr/java/latest/jre/bin/javaws - priority 200000
Current `best' version is /usr/java/latest/jre/bin/javaws.
# ll -L /etc/alternatives/javaws
-rwxr-xr-x 1 root root 140296 Dec 15  2018 /etc/alternatives/javaws
