Firefox 12 & 13 do not support Java applet under Ubuntu 12.04

[Hanine HAMZIOUI]

Reproduce:

- 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 :
/usr/lib/jvm/jdk1.7.0/jre/lib/amd64/libnpjp2.so
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.

Thanks, but please have a read of the bug reporting guidelines (https://wiki.ubuntu.com/MozillaTeam/Bugs), particularly the section "Hangs, or excessive CPU usage" and it's first sentence: "If Firefox or Thunderbird appears to completely lock up, you must provide a stacktrace of the hung process with your bug report. In most cases, hangs are quite random and non-reproducible, so please don't submit reports without this information."

In future, please read the bug reporting guidelines before submitting a bug. We do ask you to do this on the bug submission form
