Bug 32418: Add a configure flag to load policies only from the local policies.json
Add a configuration flag to make Enterprise Policies mechanism only consult a policies.json file (avoiding the Windows Registry, macOS's file system attributes, and /etc/firefox/policies/policies.json on other OS).
We avoid system policies because their proxy settings override our preferences, however updates can be disabled only with enterprise policies, so we allow them from a local file as a trade off. --- browser/config/mozconfigs/base-browser | 1 + .../enterprisepolicies/EnterprisePoliciesParent.jsm | 13 +++++++++++-- toolkit/components/enterprisepolicies/moz.build | 3 +++ toolkit/moz.configure | 18 ++++++++++++++++++ 4 files changed, 33 insertions(+), 2 deletions(-)
