Bug Fix(es):
* Previously, passwords saved in the Firefox browser and encrypted by a
master password were erased when Firefox was exited. This update ensures
that NSS files used to decrypt stored login data are handled correctly. As
a result, the affected passwords are no longer lost after restarting
Firefox. (BZ#1638082)
