I was checking things in preparation of removing firefox.x86_64 and installing firefox.i386 on my x86_64 machine when I discovered that both are already installed: $ rpm -qa --qf '%{name}-%{version}-%{arch}\n' firefox firefox-1.5.0.7-x86_64 firefox-1.5.0.7-i386 but then also: $ rpm -qf /usr/bin/firefox firefox-1.5.0.7-8.fc6 firefox-1.5.0.7-8.fc6 I suspect that firefox.x86_64 gets started though I have'nt quite discovered how yet. What happens if I install i386 plugins? Does some kind of magic happen to make firefox.i386 startup then. It might be that the shell script /usr/bin/firefox produces the magic but I am no great hero when it come to parsing shell scripts. Or do I have to remove firefox.x86_64 first? Alexander
