FF not using the latest installed JRE?{resolved}

[System_Error]

I can open applets fine in IE, and it must be using the latest JRE I have installed because the newest icon for the console shows up(do you know what im talking about?)..Then, once I try to open an applet in FF I get an exception, and I notice that it's the old icon appearing in the system tray, which tells me the old JRE is wanting used.

Here is the exception being thrown:

java.lang.UnsupportedClassVersionError: MortgageApplet (Unsupported major.minor version 49.0)

I've looked in the options of FF but cannot find any option to use the latest jre, but java is enabled.

If anyone can help(can't image who that would be) please do!
