I checked it out and here's what I found:


# yum list xulrunner*

# rpm -ql xulrunner | grep -i xpcom /usr/lib/xulrunner-1.9.2/libxpcom.so
/usr/lib/xulrunner-1.9.2/modules/XPCOMUtils.jsm
/usr/lib/xulrunner-1.9.2/regxpcom

So, that would seem to be in order.

I stumbled upon an interesting twist here, however.  The desktop launcher command was:  /usr/bin/firefox, which gave the offending response that XPCOM could not be loaded.  I noticed that the command on the browser launcher on the Panel was:  /usr/lib/firefox-3.6/firefox   and this works just fine.  Firefox starts without a problem.

While I now have a way to launch Firefox, the question remains, is this XPCOM this an issue that will affect any other applications, or is it now moot?

Thanks,
Herb
