After updating to Safari Version 12.0, the Java Plug-in under Safari > Preferences... > Websites > Plug-ins is no longer listed and therefore Java Applets cannot be ran in unsafe mode. Is there a way to enable the Java Plug-in or to run Java Applets anyway (on macOS)?

Update to Safari 12.0 - Java Plug-in no longer listed

Safari 12 no longer supports java. As someone mentioned on the apple discussion forums one of the workarounds is to switch to Firefox version v52.9ESR. It is important to (quickly) disable updates within the Firefox preferences or it will update to a newer version that also doesn't support Java. Worked for me.
