Legacy Command editing

[Tha D0od]

I use XFCE exclusively in all my Slackware installs.  It's fast, it's clean, 
it's lean and mean.

Anyway, this problem never bothered me much until recently.  If I save my 
session with a mozilla or firefox browser open, when I restart XFCE after 
logging out, the browsers don't come up again.

I manually fixed this by editing the file ending in :0 in ~/.cache/sessions 
from firefox-bin to firefox.  I was wondering if there was a systemwide 
configuration file to force the session to save firefox-bin as firefox 
instead?  Or would an easier fix be to make a symbolic link to firefox-bin 
from firefox?
