PFS has been changed correctly by Moz.org to point to new vanity link http://java.com/firefoxjre for Windows platforms for manual install when PFS kicked in.
Currently, this link temporarily leads to our manual IFTW native installers. Once CR 6637304 is pushed out with 6u5 (b2), this link will lead to the new .EXEs that replaces our old .XPIs.

However, while testing, I realize that our demo applets on java.sun.com (e.g: http://java.sun.com/products/plugin/1.5.0/demos/plugin/applets.html) are outdated.
These demo pages have <object> and <embed> tags formatted a`la obsolete HTML converter's style with troublesome attributes:

pluginspage = "http://java.sun.com/products/plugin/index.html#download" and
codebase = "http://java.sun.com/update/1.5.0/jinstall-1_5-windows-i586.cab#Version=1,5,0,0"

These tag's attributes override the purpose of PFS and bring FF end-users to wrong places for Java download. These demo pages should be corrected. Basically, we want demo pages with simple formatted <applet> tags to force users to use latest JRE when possible.

We'll need help from java.com team to locate all outdated demo applets on java.sun.com and/or java.com and replace them with correct ones.
