For example, RHEL 4 currently has a bug with the Java plugin, although it doesn't cause problems at startup: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=170447 Did you try running strace? From the command prompt, strace firefox or strace mozilla This will display a log of the system calls made by Firefox or Mozilla; often, the last few calls will give a clue as to what the problem is.
