It is not broken:
1) Download this:
2) Make it executable and place it where you want to install it, or anywhere stable and symlink it later.
3) Run it.
4) It should have extracted itself, and now you will find the plugin at './jre1.6.0_12/lib/amd64/libnpjp2.so', symlink that to '~/.mozilla/plugins' or globally to '/usr/lib/mozilla/plugins' and it will work.
