A DESCRIPTION OF THE PROBLEM :
http://jmol.sourceforge.net/demo/atoms/

When i open the above URL with an Ubuntu 10.04/Java 7/Firefox, the browser
immediately vanishes with one single error message on the console

>> /usr/lib/firefox-3.6.18/firefox-bin:
>> symbol lookup error: /usr/lib/jvm/java-7-sun/jre/lib/amd64/libnpjp2.so:
>> undefined symbol: _stricmp

If i change the configuration back to Java 6, everything is fine again.

The effect is not limited to Linux 64bit systems. The same error
appears on my 32bit workstation:

>> ./firefox-bin:
>> symbol lookup error: /usr/lib/jvm/java-7-sun/jre/lib/i386/libnpjp2.so:
>> undefined symbol: _stricmp

Opera on Ubuntu doesn't crash but the Plugin gives the same error and refuses to work

>> /usr/lib/opera//operapluginwrapper-native:
>> symbol lookup error: /usr/lib/jvm/java-7-sun/jre/lib/amd64/libnpjp2.so:
>> undefined symbol: _stricmp


REGRESSION. Last worked in version 6

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
http://jmol.sourceforge.net/demo/atoms/

Open the above URL in Firefox/Opera
with either /usr/lib/jvm/java-7-sun/jre/lib/amd64/libnpjp2.so
or /usr/lib/jvm/java-7-sun/jre/lib/i386/libnpjp2.so
configured as Java-Plugin

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Firefox crashes immediately
with Opera the JmolApplet refuses to display/work properly
