Acrobat works fine. Thanks to Andy Green's directions I have nailed down the 
firefox problem to be due to a link in /usr/lib/mozilla/plugins to
/usr/java/jre1.6.0_02/plugin/i386/ns7-gcc29/libjavaplugin_oji.so plugin. 
Changing the link to /usr/java/jre1.6.0_02/plugin/i386/ns7/libjavaplugin_oji.so 
solved the problem. I found that it is thoroughly described in 
http://java.sun.com/j2se/1.5.0/manual_install_solaris.html

The thunderbird problem turned out to be missing dependency libstdc++.so.5 and 
"yum install libstdc++.so.5" solved that problem. Actually libstdc++.so.6 was on 
the system but thunderbird insists on using libstdc++.so.5 :-)

Thanks for the help and for teaching me the use of strace.
