Hi Mark,
That made me think along the lines of why are we removing the file when 
we startup, and not when we shutdown.
So here's what I did, and this seems to be working.  (Luckily 
thunderbird is failing quite consistently for me today.)

Instead of having the script run when we startup (by naming it 
S01parentlock), we make it run when we shutdown (by naming it 
K99parentlock).

That has worked for me, and to be honest, makes more sense.

Here's the revised rpm
ftp://ftp.scientificlinux.org/linux/scientific/40rolling/testing/i386/RPMS/browsers/SL_firefox_parentlock_fix-1.0-8.noarch.rpm
