Why and How to Disable Java

By October 13, 2010

Follow me on:

Whether you're a Mac or a PC user, chances are good that Sun's Java (not to be confused with JavaScript) is installed on your computer, However, chances are also good that you very seldom actually need Java. That's a good thing because Java has outpaced even Adobe Reader to become the most targeted third-party application for malicious exploit via the Web.

One easy thing you can do to avoid this method of attack is to simply disable Java. It's almost never needed for regular Web browsing. And when you do need it for that website game or calculator, just re-enable it (but be sure to turn it back off when you're done).

Or hey! Just don’t use the internet!

How how idiotic is this sentiment? How disinformed.

Java is almost never needed. If you’d prefer to have a bad security posture 100% of the time for something you need only 1% of the time, that’s certainly your choice. But security savvy people will want to keep Java disabled until those rare times it’s actually needed.

Is Java the same as JavaScript? I disabled my JavaScript because that is all that I saw to disable that was related. At first, I wondered why I could not leave a comment, until I tried enabling JavaScript. So which is which?
I followed the instructions, which I already knew about, and even though I read them carefully, I could not see Java.

Sunflower, my bad. I updated the instructions to include steps for the latest versions of Firefox, as well as other places to look for Java in Internet Explorer.

But no, Javascript and Java are not the same thing. If you disable Javascript entirely, it will break most of the websites you visit. For Javascript protection, your best course is to use NoScript (which only works with Firefox).

Gene De Lisa, the writer was being sarcastic. Look it up in the dictionary. Second, learn “how how” to write before leaving a comment — even one as idiotic as you just left.
