Oracle has just released Java 7 Update 11 including fixes to the recent
security exploits. You can update your java by going to link below
If you still have any Java 6 on your system we recommend that you remove all previously installed java including JavaFX if it is present before installing the update.
We have had a few say that their updated FireFox browser isn't working with our chat with update 11 but I personally have not been able to replicate that problem.
