We used to have a xpi download for Firefox users for both java.com and non-java.com

jre-6u10-windows-i586-jc.xpi jre-6u10-windows-i586.xpi

They were used through the Firefox plugin finder service. Microsoft/Firefox decided to deprecate the plugin finder service, for security reasons. So in 6uX, we dropped these files for .exe's with "xpi" in them:

jxpiinstall-6u10-windows-i586.exe
xpiinstall-6u10-windows-i586.exe

which are essentially copies the jre-iftw.exe with a different name. When run, these .exe's check the names of themselves and ping home that they are triggered through FF and whether they are from java.com or non-java.com.

I don't think we really need the xpiinstall-6u10-windows-i586.exe anymore. Who is really going to use this file? I can see us keeping the jxpi, so we can track java.com FF users. But I think non-java.com/FF users/vendors are just going to use our regular jre-iftw.exe.
