Firefox was updated to version 15 this week (Tuesday or Wednesday). It is updating automatically now — so you may not even be notified — which is a good thing. If you are a daily Firefox user, it’s likely you already have the update. However, if you are only a once in a while Firefox user, please open Firefox and leave it open for 10 to 15 minutes. The update should get pushed through to you.
Java, as I’ve explained before, is a helper application on your computer that makes other programs run. A loophole was discovered this week by which attackers could do harm to your computer. Oracle has now patched Java to safeguard you against this vulnerability. IF YOU ARE NOTIFIED TO UPDATE JAVA. — please do not delay.
