I mounted a tmpfs in ~/tmp and FireFox can read from there.
I haven't tried the link from /tmp to ~/tmp, but editing /etc/fstab to move /tmp to ~/tmp, then a link from /tmp to ~/tmp might be a workaround on a system with only one user.
But I also saw my first kernel panic after moving some stuff from /tmp to ~/tmp (but haven't reproduced it again), so I'm not sure this is all kosher...
