Hi, This is the output of the same ldd command you gave, on a RHEL 4 32 bit machine. As far as I can see they are the same other than the hex number at the end. # rpm -qi firefox Name : firefox Relocations: (not relocatable) Version : 1.5.0.12 Vendor: Red Hat, Inc. Release : 0.10.el4 Build Date: Fri 01 Feb 2008 07:51:56 AM CST Install Date: Tue 04 Mar 2008 01:16:12 PM CST Build Host: hs20-bc1-7.build.redhat.com Group : Applications/Internet Source RPM: firefox-1.5.0.12-0.10.el4.src.rpm Size : 31919449 License: MPL/LGPL Signature : DSA/SHA1, Mon 04 Feb 2008 01:28:04 PM CST, Key ID 219180cddb42a60e Packager : Red Hat, Inc. <http://bugzilla.redhat.com/bugzilla> URL : http://www.mozilla.org/projects/firefox/ Summary : Mozilla Firefox Web browser. Description : Mozilla Firefox is an open-source web browser, designed for standards compliance, performance and portability. I have no idea how stable this RHEL firefox it, because I don't use the machine for web browsing. I can point it at a URL or two if there are specific web pages that usually crash your firefox.
