Hello,

After install my Ubuntu 12.04 and setup it I try to access my online banking. I couldn't access it, because the Java wasn't there. So here is how to Install Java on Ubuntu 12.04 (64 bits) and use it on firefox.

Install:

$ sudo apt-get install icedtea6-plugin

Now to have your Java working on firefox use:

$ sudo apt-get install icedtea-plugin

Close your browser, open and enjoy.

Best Regards,
Matheus
