Enable Java in Firefox 3

Java was created by Sun Microsystems. Many websites use Java for interactive content, such as online games and chat rooms. If you don't have Java enabled in Firefox 3, then some websites will not work. You won't be able to play online games or chat in chat rooms, including the ones that are 3D, such as those in Second Life and Vivacity. If you use Mozilla's Firefox 3 web browser, then you'll need to know how to enable Java so that you can easily access and use these features.

This article will help you to Enable Java in Firefox 3.
Instructions

1. Click on your Firefox 3 shortcut to open your browser.
    
2. Click on the "Tools" menu, and then click on "Options" and then the "Content" panel. Make sure that the box titled Enable Java has a check mark in it; if it doesn't, click on the box.
    
3. Visit the Java Tester site and click on "test the version of Java your browser is using" link at the top of the page. This will test whether or not Java has been enabled and is working in your Firefox 3 browser. Assuming Java is now enabled and working, you'll see a pink box, and inside will be words like, "Java Version 1.6.0_01 from Sun Microsystems Inc."
    
4. Remove outdated Java plugins from your Firefox plugins folder if Java still isn't working. Go to the "Tools" drop-down menu, and select "Add ons," and then the "Plugins" panel. If there are plugins that are from earlier versions of Java, such as Version 1.5.0_01, for example, delete them, then test again at Java Tester.
