Ubuntu :: 32-bit And 64-bit Firefox At The Same Time?

Is it possible to run both a 32-bit version of Firefox and a 64-bit version of Firefox at the same time?Here is my problem:WebEx requires 32-bit for Ubuntu Linux. But, I need a 64-bit OS for other software that I run.I also have 64-bit Java running Eclipse and a couple of other Swing applications with no problems. So, I don't really want to switch everything over to 32-bit.Here is what I was able to do:- I can create a separate Firefox Profile for WebEx. I launch it using the -P switch.- I can have multiple Firefox Profiles open at the same time with the --no-remote switch.- I downloaded the 32-bit version of Firefox from the Firefox website and extracted it into a directory underneath my home directory.

- I can run that version of Firefox, and I am assuming that is a 32-bit version running.The problem is that it does not load any of my plugins because they are 64-bit. I see in the terminal output these messages:LoadPlugin: failed to initialize shared library /usr/lib/mozilla/plugins/librhythmbox-itms-detection-plugin.so [/usr/lib/mozilla/plugins/librhythmbox-itms-detection-plugin.so: wrong ELF class: ELFCLASS64]I have a 32-bit version of Java installed at ~/bin/java/jdk1.6.0_18, and I created a link to the plugin in my 32-bit firefox plugins directory:~/bin/java/firefox/plugins$ sudo ln -s /home/skp/bin/java/jdk1.6.0_18/jre/plugin/i386/ns7/libjavaplugin_oji.so libjavaplugin_oji.soFrom what I can tell, Firefox is not looking in that directory for Java.
