Note: There are no changes to the ADMX templates in this release. I bumped the version to be consistent. There is no need to move to these templates if you are using versions below v5.6. You'll see some XML changes, but they are all cleanup.
Note: While these templates will work for Firefox ESR 102, they might contain new policies that are not in Firefox ESR 102. If you need to manage Firefox ESR 102, you should use v4.12
I'm no longer using a versioned README for documentation, I'm using a GitHub page which is available at:
https://mozilla.github.io/policy-templates/
You can search on the corresponding version of Firefox (121 in this case) to see version specific policy changes.
If you need to see version specific documentation, you use this link:
https://github.com/mozilla/policy-templates/blob/v5.6/docs/index.md
Preferences - The preferences security.disable_button.openCertManager and security.disable_button.openDeviceManager can now be set via policy. They must be locked to function correctly.
