firefox (31) broke my java setup again


Installed firefox 31 today. All my java apps stopped. So I typed:

Code:
sudo cp ~/Downloads/jdk1.7.0_65.tar.gz /usr/lib/jvm/
cd /usr/lib/jvm/
sudo tar zxvf jdk-7-linux-x64.tar.gz
cd ~/.mozilla/plugins/
ln -s /usr/lib/jvm/jdk1.7.0_65/jre/lib/amd64/libnpjp2.so
export JAVA_HOME='/usr/lib/jvm/jdk1.7.0_65/bin/'
sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.7.0_65/bin/java 400
<clickLaunch>
;; no java anywhere
What'm I missin?

BTW: update-alternatives doesn't have enough functions to justify its existence IMHO. I should be able to type one command and get ALL the java stuff defined...javac,javadoc,jps,javah, etc. etc. And then I should be able to swap to icedtea with another single command. If I set symlinks up correctly, I can do that (well,maybe a couple). no update-alternatives need apply.

UPDATE:
Code:
sudo ln -s /usr/lib/jvm/jdk1.7.0_65/ /usr/lib/jvm/default-java
sudo ln -s /usr/lib/jvm/default-java/jre/lib/amd64/libnpjp2.so /usr/lib/jvm/default-java/jre/lib/amd64/libnpjp2.so
ln -s /usr/lib/jvm/default-java/jre/lib/amd64/libnpjp2.so /home/sdl/.mozilla/plugins/
Chromium works GREAT! S'what is firefox' problem?
Does firefox need something set inside about:config ? I remember you need a hard proxy link in about:config on kubuntu. Does anyone know what var to set?

__________________________________________
OK, I now have at least a partial answer:
For the latest versions >1.7.0_51, the default security settings are set
so high that almost nothing runs.
WORSE: Oracle gives you the message that the plugin is not installed!! This
is an error. It is installed. Its just the security.
The fix is to run /usr/bin/jcontrol and set the security to lowest level OR
set security on a website by website basis. Both are bad because they allow
signed applets to do anything you can do from bash. (if I understand this)
This applies to chromium-browser. See the details at
http://javatester.org/version.html
I still can't get anything to run in my firefox.
