It is important that you read the following advisory:
There may come a time when you discover you need to use Java. Before you use it, it is highly recommended that you check first to confirm whether it is up-to-date. You can do so here. NOTE: If you install a new version from Java's web site, please be sure to un-check the box that installs the "ASK.com" toolbar. It is not needed.
You should procede with the steps below ONLY if you are certain of the safety of the web site or web program that is asking you to enable Java. It is not recommended that you do this for all your broswers, only the one you will use for trusted sites and web programs that require Java.
- If you previously used either the Java Control Panel (Windows) or the Java Preference (Macintosh OS 10.7.3 and up) to disable Java in all of your browsers, you will need to re-enable Java and then turn off the Java plug-in in the browser you will use for day-to-day browsing. It is only in this manner that you'll be able to independently control Java in each of your browsers. If you are uncertain as to whether you turned it off globally, the steps below will take you to the appropriate control panel (Windows) or preference (Macintosh) where you can determine its current status.
- If you did NOT disable Java using the control panel or the preference, then procede to the section below labeled "Turning Java on in an individual browser".
Known sites and applications that require Java.
Globally turn Java on using the Java Control Panel (Windows) or the Java Preference (Macintosh)
IMPORTANT NOTE: This is a two part process! Once you have turned Java on globally, you must turn it off for the individual browser(s) you intend to use for day-to-day browsing. See the link at the bottom of this page for disabling Java in an individual browser.
