I have an FC5 server which has exported /home via NFS. Client machines automount /home.
Using /home as a network share is inherently insecure, and for reasons you have just discovered, doesn't work very well.
Can multiple instances of firefox actually share a single profile? Can anyone else confirm this behavour?
Firefox, and many other programs, use a locking mechanism to determine if there is already another instance running, and (as you have discovered) will not launch another instance if there is: ~/.mozilla/firefox/<profile>/lock If you are sharing a $HOME directory among multiple machines or users, you will invariably run into gotchas like this, and with many other dotfiles too. Best solution: create a share on its own filesystem, or at least away from $HOME, mount it, set the correct perms, set the required SELinux contexts (if applicable), re-export, and reconfigure NFS. IMHO FC5 desperately requires a simple tool (with GUI?) to simplify this process, including opening firewall ports, etc. system-config-nfs just doesn't even come close. -- K.
