Firefox essentially does not support running NSS in FIPS mode any longer. This
has always been the case on Android from what I can tell and it has been the
case on OS X since at least version 34 (see bug 1047584). It became the case on
Windows as of version 53 (see bug 1295937). Unfortunately, before this patch,
if a user attempted to run an affected version of Firefox using a profile
directory containing an NSS database collection that had FIPS enabled, NSS
initialization would fail and fall back to running in no DB mode, which had the
side-effect of making any saved passwords and certificates unavailable. This
patch attempts to detect and work around this failure mode by moving the
PKCS#11 module DB (which is where the FIPS bit is set) to a backup location and
basically running with a fresh, non-FIPS module DB. This allows Firefox to
initialize NSS with the preexisting key and certificate databases available.
