>Description:
After firefox is updated to 74.0, language packs provided by
firefox-l10n package are no longer loaded by default and default
en-US is always used even LANG is set as ja_JP.UTF-8 etc.
[Tools] -> [Add-ons] menu does not show "language packs" either.

>How-To-Repeat:
See above.

>Fix:
Maybe this upstream's "extension sideloading" change on
firefox 74 affects this:
 https://blog.mozilla.org/addons/2019/10/31/firefox-to-discontinue-sideloaded-extensions/

It looks working to move all langpack xpi files
from current ${PREFIX}/lib/firefox/browser/extensions
to ${PREFIX}/lib/firefox/distributions/extensions
as upstream scripts do:
 https://searchfox.org/mozilla-central/source/taskcluster/docker/firefox-flatpak/runme.sh#120
 https://searchfox.org/mozilla-central/source/taskcluster/docker/firefox-snap/runme.sh#56
