FireEyes is an easy-to-use plug-in that is fully integrated with one of the most powerful Web development tools, Firebug, which is a Firefox extension. In order to install FireEyes you must:
As of October 2012, FireEyes requires Firefox version 14 or 15. Check the FireEyes FAQ page (opens in a new window) for the most current compatibility and download information.
As of October 2012, the current version of FireEyes is compatible with Firebug version 1.10.4. Check the FireEyes FAQ page (opens in a new window) for the most current compatibility and download information. Download and install the appropriate version of Firebug. Then restart Firefox.
When you are logged into WorldSpace, activate the Download icon as shown in the following figure:

When the following dialog appears, click "Install Now":

Restart FireFox once installation is complete.
Java Platform SE 5.0 (sometimes also referred to as Java 1.5.0) or higher must be installed and enabled in the browser. If Java is not enabled, or if an older version of Java is installed, then FireEyes will load but will show an error message.

If you get this error message you will need to install Java and/or enable the Java Platform plug-in for Mozilla browsers in order to use FireEyes. Go to the Java test page (opens in a new window) to test whether Java is working on your computer and what version is installed. Download the current, recommended version of Java and/or use the troubleshooting steps on the page.
If the Java test webpage shows that Java SE 5.0 or above is installed, you may need to verify that it is enabled in Firefox. From the Firefox menu, select Add-ons, and select the Plugins tab. Verify that the Java Platform plugin is installed, up-to-date, and enabled.

Once Firefox has been restarted launch the Firebug plugin by activating the Firebug icon in the far right corner of the Firefox tool bar or by pressing the F12 key on Windows. Firebug will open on the bottom portion of your browser window, and the FireEyes tab will appear in Firebug as shown in the following figure:

You are now ready to start using the FireEyes extension.
