I don't see any /dev/shm on my system.  Benny, did you mean /var/shm ?

I fixed /etc/fstab for the /tmpfs /var/shm line , and, without rebooting, did
mount_tmpfs tmpfs /var/shm .

That enabled Firefox to start but leaves me curious how Seamonkey could run without this fix.

That fix also enabled www/vimb to start (looks interesting with useful features but carries a learning curve), enabled www/midori to access web pages.

Qutebrowser couldn't do anything because of an insecure, outdated qt5-qtwebkit (as close as I can remember the name).
