Public bug reported:


- Open Firefox 12 or 13
- Go to :  http://java.com/en/download/testjava.jsp
- Normally a java applet should appear informing the user that Java is working.

Instead, the web browser hangs a while and freezes. Obliged then to
force quit.

I already enabled Java for firefox by removing ICEDTEA plugin and adding a symbolic link to the correct plugin :
in ~/.mozilla/plugins
And typing about:plugins reveals that indeed Java is installed in Firefox.
I tried with all firefox extensions disabled but in vain.

System: Ubuntu 12.04 on AMD64 laptop.
~$ java -version
java version "1.7.0_04"
Java(TM) SE Runtime Environment (build 1.7.0_04-b20)
Java HotSpot(TM) 64-Bit Server VM (build 23.0-b21, mixed mode)

Java works fine in Google Chrome / Chromium  / Midori / Opera.

Thanks in advance for your interest.
