Note: While these templates will work for Firefox ESR 128, they might contain new policies that are not in Firefox ESR 28. If you need to manage Firefox ESR 128, you should use v6.11
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 (142 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/v7.2/docs/index.md
This release updates the following policies:
Permissions - Support for setting permissions for sharing the screen has been added.
EnableTrackingProtection - Support for setting the default mode has been added as well as support for suspected fingerprinters.
For more information about Firefox 142, see the enterprise release notes.
