How to Disable Java in Three Common Browsers

The ongoing security problems with Java mean that many people will want to disable the Java plug-in for their web browsers. Here is how to do it for the most common browsers.

Google Chrome

  1. In the Chrome address bar enter: chrome://plugins
  2. Find the entry for the Java plug-in and click “Disable”

Firefox

  1. Open the Firefox menu
  2. Click “Add-ons”
  3. On the left side of the Add-ons manager that opens, select “ Plugins”
  4. Click “Disable” by the entry for Java

Firefox may have already done the disabling automatically

Internet Explorer

Disabling Java in the various versions of Internet Explorer (IE) is more complicated than it seems at first. You can use the IE Add-ons manager to disable  “Java(tm) Plug-in 2 SSV Helper” and "Sun Microsystems -Deployment Toolkit " but that isn’t sufficient. There are apparently multiple ways that Java can be invoked from IE. It is sufficiently complicated that Microsoft has a special article on how to disable the Java plug-in for Internet Explorer. It isn’t pretty. The article involves Registry editing and its gory details are at this link. You can also check out this Homelands Security bulletin about IE.

For Opera: Type opera:plugins in the address bar and disable java

Revo Uninstaller Free has yet again proved itself an essential app on my computers. I've now read the latest bulletins re Oracle's problems and decided that merely disabling Java isn't enough: might just as well uninstall as disable. Seeing as how some posters on these current Java-related threads seem to be anxious about uninstallation, this is my experience on my desktop Vista OS:

1. Open Revo. It identified two Java installs, Java 6 Update 29 and Java 7 Update 9.

2. Revo uninstalled Java 6 Update 29 in 'moderate' mode and after the Windows uninstaller had completed its task, found no registry left-overs. Switching back into 'advanced' mode, and Revo found 21. They were all Java-related. I deleted the lot.

3. Revo uninstalled Java 7 Update 9 in 'moderate' mode and after the Windows uninstaller had completed its task, found 12 registry left-overs. They were all clearly Java-related. I deleted the lot. Switching back into 'advanced' mode, and Revo found 71. They were all AppData\Google Update 1.3.21.123. They're not critical to the operation of my machine. I deleted the lot.

Time taken to clear this computer of Java installations: 5 minutes. As ever, Revo -- used sensibly -- is pure gold.

It's not necessary to uninstall java, that is in case you are running some softwares that requires java. The exploits that were found were targeted at the browsers only. You are having two versions of Java because you didn't uninstall the previous version before installing the newer one. This is the recommended procedure while installing java.

I know my pc ignorance will show, but, other than to update, why would one remove Java? Java is a total mystery for me. I should go read up on it.
I would like to add something here. I was having some issues which I thought might pertain to my Java. I kept getting a notice with that pc icon that looks like it's hungover. I checked to see if I had the latest version and it said I did. There was some message about viewing 'all versions', so, I clicked on it and was able to download a version for 64-bit, which I run. That did the trick!
This is probably common knowledge, but, just in case...

Thanks,

Su

Beware of unwanted bundled components and system changes when installing Advanced Uninstaller Pro. MC - Site Manager.

Yesterday's tip of using JavaRa seems to be the easiest way to disable Java - remove it! Then when you need it, you can do a clean install.

by Nodrog on 17. January 2013 - 14:51  (104577)

I agree, and the JavaRa download does not require installation so there is no problem with bundled bloatware or system changes as flagged up with the other program mentioned above.

The program can do more than just remove Java, including version checking, removing older versions etc.

Is it not better to simply disable the browser plug-in from the Java control console, especially in view of the complications with IE?

Use Control Panel>programs>Java to access it, then click on security and uncheck the box and restart the browser. You can re-enable it any time you really need to use it or if you're satisfied it is safe.

hi laurie, thanks for the tips. i need to use java for stock market quotes. i have tried the updates but they dont work for for me. even the brokerage could not get the new updates to work. are older versions of java ok to use? or can you run your browser sandboxed and be ok? thanks

by Jojo Yee on 17. January 2013 - 15:10  (104580)

Hi Clas, if you've updated Java to the latest version, try also update JavaFX that works along with it. This solved the problem for me when using Chrome to run stock market quotes and other websites relying on Java.

by clas on 17. January 2013 - 16:57  (104588)

hi jo, thanks for the tip. i think i will make an image of this system first so if it does not work i can just restore it. then i will update the java and try installing fx and give it a try. thanks, i am always looking for ways to solve these little problems in life...hahah...

Old versions are unsafe. Running the browser sandboxed is a good idea.

by Computer Illiterate on 17. January 2013 - 10:20  (104562)

Can you explain why I cannot simply delete the programme through Control Panel?

by v.laurie on 17. January 2013 - 14:43  (104575)

You have asked a good question. Using the Control Panel is an option. But that can leave behind old Java versions. It also may not affect all browser plug-ins.

In Opera, f12>Disable Java

by Fairportfan on 17. January 2013 - 15:11  (104581)

Didn't work in my copy of Opera - all that it gives me a shot at enabling/disabling is JavaScript. Not the same thing.
