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)");
