Jim Hamm grabs our attention with important info on Java. "in case you didn't see it, here is another article discussing Java, and how to remove or disable Java in your browser of choice. Some time ago I had disabled Java in the three browsers I use: Safari, Firefox and Chrome. I happened to be using Firefox when reading this article, so I thought I'd check the Java plug-in. Ouch! Sure enough, it was enabled again. How, I don't know. Perhaps when the browser itself is updated. I immediately disabled Java again.
That's probably why the author of this article recommends removing Java -- because somehow it can become enabled again, which is not a good thing from a security standpoint. Following is a summary from the article on how to disable Java.”
How to isolate Java
Isolating Java means leaving it on your Mac, but removing it from your browser except when you want it to run. Apple now does this by default for all Macs (10.6 and later) and will re-isolate it after about a month even if you've turned it back on. Isolating Java is a bit more complex now that Apple has removed the Java preferences utility from Lion and Mountain Lion.
If you run Java 6 (the Apple supplied version), you need to restrict it on each of your browsers. In Google Chrome, type chrome://plugins in the address bar and click the link to disable Java. In Safari, go to Safari > Preferences and uncheck Enable Java in the Security pane. In Firefox go to Tools > Add Ons > Plugins and uncheck Java Plug-In.
