Firefox 3.6 missing Tools>>Options>>Content >>Java (where did it go?)

I was trying out the recommended wifi stumbler
(http://tools.meraki.com/stumbler) but it needs Java which I've had
installed for years on Windows XP SP3.

However, in Firefox 3.6, Tools>>Options>>Content>>Java is MISSING!

There's Tools>>Options>>Content>>JavaScript but no line item for Java (I'm
sure it used to be there before I upgraded to Firefox 3.something).

Where did Tools>>Options>>Content>>Java go?
