On my 64-bit Ubuntu 7.04 system, Firefox 22.214.171.124 has no Java plugin available, however I still see the Cortado player in the list of available players when activating the OggHandler player. When selecting it, Firefox shows a 'missing plugin' icon in the window and brings up the yellow bar recommending installing a Java plugin.
Firefox is returning true for navigator.javaEnabled() if Java support is _enabled_ in preferences even though no Java plugin is there in the browser, so no Java will actually work.
If it's possible to probe for actual presence or absence of Java support, that might be more user-friendly than a big "ha ha, the thing you selected doesn't exist". :)
Fixed in r25056.
