I am not using iceweasel from experimental.  But I am using the same
version from Backports on Stable Squeeze 6.  Works for me.

What is the output of this for you?

  $ update-alternatives --display mozilla-javaplugin.so
  mozilla-javaplugin.so - auto mode
    link currently points to /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/IcedTeaPlugin.so
  /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/IcedTeaPlugin.so - priority 1071
  Current 'best' version is '/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/IcedTeaPlugin.so'.

  $ dlocate /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/IcedTeaPlugin.so
  icedtea-7-plugin:amd64: /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/IcedTeaPlugin.so

The above from my machine shows that it is handled by the
icedtea-7-plugin:amd64 package.

Note that Java != Javascript.  The name Javascript was simply an
attempt to ride on the wave of marketing for Java.  It has worked.
Many people think they are related.  They are not.

The world of Java seems fraught with programs that are version
specific.  Perhaps you are hitting one of those cases.  Perhaps Java
in general is working but a particular program is version specific and
doesn't match your version?
