How do I tell if I have Firefox 32 bit or 64 bit?
I am trying to update my java add on, but I can not find ANYWHERE which version, 32 bit or 64 bit, of Firefox to know which one to install.

You appear to be running 32bit. Mozilla Firefox isn't currently offered in 64bit on Windows, aside from the Nightly testing releases.
Your User Agent (check it from Help -> Troubleshooting Information) does indicate which version you're running, in a roundabout way - WOW64 is what Windows calls running 32bit applications on 64bit Windows. If you were running 64bit Firefox, you would see x64 instead.
