NOTE: There is a regression in Firefox 81 and Firefox ESR 78.3 that breaks legacy preference policies on Windows when using GPO. We don't have a timeline for a fix yet, but the workaround right now is to switch to using the new Preference policy. I apologize for the inconvenience.
Note: While these templates will work for Firefox ESR68, they contain new policies that are not in Firefox ESR 68. If you need to manage Firefox ESR 68, you should use v1.17
The README that corresponds to this release is:
https://github.com/mozilla/policy-templates/blob/v2.3/README.md
This release updates the following policies:
Preferences - Added support for specifying arbitrary preferences. Not all preferences are included, but most are. We will be continually adding more prefixes.
Preferences that start with the following prefixes are supported:
accessibility.
browser.
datareporting.policy.
dom.
extensions.
geo.
intl.
layout.
media.
network.
places.
print.
ui.
widget.
as well as the following security preferences:
security.default_personal_cert
security.insecure_connection_text.enabled
security.insecure_connection_text.pbmode.enabled
security.insecure_field_warning.contextual.enabled
security.mixed_content.block_active_content
security.osclientcerts.autoload
security.ssl.errorReporting.enabled
security.tls.hello_downgrade_check
security.warn_submit_secure_to_insecure
