Java Plugin in Firefox, and Vista 64 Bit

I recently started using Windows Vista 64 bit, and was having problems getting java working on Firefox (32 bit, official build). It worked fine on Internet Explorer, and all the settings seemed right. To get it working, I had to go into the Java Control panel (if Java is not in windows control panel, go to something java with IE and right click it at the bottom on the taskbar to get to it), then go to the "advanced tab", then to the Java plug-in menu, and disable the next-generation Java plug-in. Firefox immediately started working after that.

Hopefully this is useful to someone.
