In case you missed it there is an unpatched security flaw in Java that is being actively exploited on the internet right now.
The vulnerability affects both Windows, Apple OSX and Linux versions of Java irregardless of what browser you use. Oracle has not announced any plans to patch the vulnerability with an out of cycle patch (The next scheduled Java patch is months away).
Now might be a good idea to disable Java in your browser. Usually you can do this by finding the settings for addins. In chrome you have to go to the URL chrome://plugins/ and find Java in the list and disable it (There is no item for this in the menus as far as I can tell).
