What parts of mozilla use DBM ??

[Nelson B. Bolyard]

Mozilla contains an implementation of DBM.  NSS and PSM use DBM.  
What other parts of mozilla use DBM?

I ask because I've recently found several bugs (about 5) in DBM, 
(see http://bugzilla.mozilla.org/show_bug.cgi?id=69753 for the info)
and I'm trying to find out what else is impacted by these bugs.
