Firefox for Enterprise Community Forum

I am trying trying to install the keeper extension via intune but am having trouble with the oma-uri. It looks right to me but I might be missing something. Prior to running this I followed https://mzl.la/3vYAIYT and added the Firefox ADMX. Both run successfully but it does not add the extension. Firefox version 116.0.3

OMA-URI: ./Device/Vendor/MSFT/Policy/Config/Firefox~Policy~firefox~Extensions/ExtensionSettings

String: <enabled/> <data id="ExtensionSettings" value=' {

 "*": {
   "blocked_install_message": Opps, this may have been a mistake reach out to IT.",
   "install_sources":["about:addons","https://addons.mozilla.org/"],
   "installation_mode": "allowed",
   "allowed_types": ["extension" ,"theme"]
 },
 "KeeperFFStoreExtension@KeeperSecurityInc": {
   "installation_mode": "normal_installed",
   "install_url": "https://addons.mozilla.org/firefox/downloads/latest/keeper-password-manager/latest.xpi",

"default_area": "navbar"

 },

}'/>

Are these supposed to look different, or am I just doing something wrong? In the image I included here, SanitizeOnShutdown and Preferences look different from FirefoxHome and look incorrect. I removed other policies to make this simpler, but all of the other policies with multiple policy values look just like FirefoxHome. It appears that SanitizeOnShutdown is at least working since my history is indeed getting cleared on shutdown, but I'm unsure whether this actually works when I set these to the settings they should be since they should all be false other than Locked. Am I doing something wrong here or are these two policies supposed to look like that for some reason? Thank you in advance for the help!

I am using the intune preview feature which allows you to import admx/adml instead of using the custom injection method. Everything works far better then with the injection method, except for one settings:

ExtensionSettings this setting is working when I have only one setting set (ex):

{"someplugin@test.com": { "installation_mode" : "allowed" }}

If I add a second line to the entry:

{"someotherplugin@test.com":{ "installation_mode" : "allowed"}}

I understand this is a new feature, but if I had the correct format that would work for HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox\ExtensionSettings to allow two plugins to work I belive I shouldn't have any issue getting the admx feature to do this, I even tried manually editing the registry setting and it breaks whenever I add the second line to it.
