# - MOZ_APP_DISPLAYNAME: Used in user-visible fields (DLL properties,
# Mac Bundle name, Updater, Installer), it is typically used for nightly
# builds (e.g. Aurora for Firefox).
# - MOZ_APP_PROFILE: When set, used for application.ini's
# "Profile" field, which controls profile location.
# - MOZ_APP_ID: When set, used for application.ini's "ID" field, and
# crash reporter server url.
# - MOZ_PROFILE_MIGRATOR: When set, enables profile migrator.
# The following environment variables used to have an effect, but don't anymore:
# - MOZ_APP_VERSION: Defines the application version number. This was replaced with
# the contents from the version.txt file in the application directory, or
# browser/config/version.txt if there isn't one.
# - MOZ_APP_VERSION_DISPLAY: Defines the application version number. Used
# in the "About" window. This was replaced with the contents from the
# version_display.txt or version.txt in the application directory, or
# browser/config/version_display.txt.
# For extensions and langpacks, we require a max version that is compatible
