I would suspect it's a Java-related problem, too. I often see people complain about their Mozilla/Firefox crashing as it loads a site that uses Java. Almost all the time it's either symlinking the wrong version of Java plugin file or copying the Java plugin file instead of symlinking it.
Which the version of JRE/JDK are you using? Go to your Mozilla plugins directory and run the following command:
ls -l libjavaplugin_oji.so
What is the output from the command?
Also, which version of Mozilla are you using?
