Disable Java in Safari

Few sites need Java. Disabling Java in the web browser has always been a good idea.

As of August 2012, a new security hole in Oracle’s Java 7 makes it even more of a good idea to disable Java (not Javascript), even though a patch was released to fix that particular security issue. (Java 7 is something you’d have to download from Oracle’s web site, but all versions of Java carry risks).

Do not confuse the confusingly named Java and Javascript. These are completely different beverages.

Even the most basic sites often require Javascript to run properly, it pretty much needs to be enabled at all times. Javascript is NOT Java.
