Policy templates for Firefox 117 and Firefox ESR 115.2

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

Note: I strongly recommend reading the enterprise release notes for this version of Firefox. This version is the last 102 ESR and we are dropping support for some older operating systems.

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 (117 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/v5.2/docs/index.md

This release updates the following policies:

ExtensionSettings - Documentation for default_area has been added (The functionality was added in Firefox 113, but the documentation was missing).

I have added new "JSON on one line" policies in the GPO for all of the policies that support JSON. This is because the new Microsoft support for Custom AMDX and ADML templates (https://learn.microsoft.com/en-us/mem/intune/configuration/administrative-templates-import-custom) requires you to explicitly add a new line in the UI for each line of your JSON, but it limits lines to 1024 so you can't put all your JSON on one line.

I'm hoping they fix this at some point, but this is the best workaround I could come up with.
