How To Uninstall or Disable Java in Web Browsers

Java is definitely getting a bad rap these days due to several security vulnerabilities, and Oracle doesn’t seem able to release patches fast enough. If you don’t need Java, you might as well just uninstall it. If you do need it for a desktop program, here’s how to disable it in web browsers.

Why Should I Disable Java from My Browser?

For one, US-CERT (US Computer Emergency Readiness Team) notes multiple vulnerabilities and recommends disabling it in browsers.

Last year a Zero Day Exploit was announced that allows your system to be vulnerable to malware. A manual update patch fixed the issue, but another new exploit was discovered in January of this year. In fact, just recently hacks to employee computers at Facebook and Apple, were due to a Java exploit. Unless you absolutely need it for a certain program you’re running, I recommend just axing it all together. Simply put, for the home user, if you don’t know if you need Java, you don’t.

Java also tries to install the worthless Ask toolbar and other crap on your computer,that fact alone is a good enough reason to kill it.

Java Desktop Programs

Desktop programs that run on Java aren’t necessarily the biggest concern — although they are vulnerable. The most troublesome aspect is the Java in your web browser. If you’re running a Java desktop program (Minecraft or Android SDK for example), make sure to keep it updated and install security patches. But if you don’t need it, just get rid of it.

To keep it up-to-date, open the Java Control Panel, select the Update tab, and the Advanced button. Then set Automatic Update to check Daily.

Disable Java in Your Web Browsers

If you have Java installed for a desktop program, you’ll still want to disable it in your browser. A new setting introduced in Java 7 Update 10 is the ability to disable it for all of your browsers, while still allowing it to work for your desktop programs.

In the Java Control Panel, click the Security tab. Then uncheck “Enable Java Content in the Browser” and click OK. This is the easiest way to make sure it’s not enabled in all of the web browsers you have installed.

uncheck Enable java

Disabling Java individually in the major browsers is easy too. Here’s a rundown for disabling it in Chrome, Firefox, Internet Explorer, Opera, and Safari. After disabling it in your browser, if there’s a site you need it for, you’ll get a message asking you to download it. If you just have a game on a site that you love that use Java, just find a new one.

Google Chrome

In Chrome, getting to it via Settings is a arduous process. Here’s the easiest way to get right to where you need to be:

  • Open Google Chrome and type: chrome://plugins into the address bar.
  • Scroll down the list and then click Disable. And close out of the tab.

Also note, that if you do need Java, you can find critical security updates for it here too.

Java is NOT the same as JavaScript! In fact they are two very different programming languages. Java is an object oriented language that needs to be compiled. JavaScript on the other hand is code that’s run in a browser only. For more information on the differences, check out this Java site for a brief explanation.

    I don’t understand?……..

    Taken from the java webpage……………

    ” Java is a programming language and computing platform first released by Sun Microsystems in 1995. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere! “
