Contributed by Mary Sutton, CEHS

Based on the following article http://www.infoworld.com/t/web-browsers/how-disable-java-in-your-browsers-210882

1.  Update Java app to Java 7 update 11. This version installs a Java Control Panel. http://java.com/en/download/manual.jsp


2.   If you don’t need Java at all, disable Java through Java Control Panel. This will disable Java in all web browsers installed on computer. (http://java.com/en/download/help/disable_browser.xml)
Disable Java through the Java Control Panel

Note: The example shows Java Control Panel for Java 7 Update 11

In the Java Control Panel, click on the Security tab.
Deselect the check box for Enable Java content in the browser. This will disable the Java plug-in in the browser.
Click Apply. When the Windows User Account Control (UAC) dialog appears, allow permissions to make the changes.
Click OK in the Java Plug-in confirmation window.
Restart the browser for changes to take effect.
 
3. If need Java for UNL sites (some components in Blackboard, Firefly, etc) then disable Java in all web browsers preferences menu, except for Chrome. By default, Chrome prompts user before running Java on a specific page. Use Chrome to run any necessary Java pages. (http://java.com/en/download/help/disable_browser.xml)

Java for Mac OS X 10.6, Update 12 is available for Mac OS X v10.6.8 and Mac OS X Server v10.6.8.
