It said Java plugin was vulnerable. After successful java install, I no longer have a java plugin in Firefox's list. It can't verify java versions match.
If not having a java plugin that Firefox lists is a problem (and I think it is), I think I know how to at least get started installing the plugin from a file on my drive using the options button on some page or other. But do I install java.exe or javacpl.exe (Java control panel) or is neither one of them the plug in? If not, how do I get a plugin for java to install in Firefox? It would think it would be one of the files that got installed with Java.
