LegacyProfiles

Disable the feature enforcing a separate profile for each installation.

If this policy set to true, Firefox will not try to create different profiles for installations of Firefox in different directories. This is the equivalent of the MOZ_LEGACY_PROFILES environment variable.

If this policy set to false, Firefox will create a new profile for each unique installation of Firefox.

This policy only work on Windows via GPO (not via policies.json).
