Hello, in Firefox browser, my organization has always blocked all extensions except for ones we allow through OMA-URI ./Device/Vendor/MSFT/Policy/Config/Firefox~Policy~firefox~Extensions/ExtensionSettings.

About a month ago this stopped working and our end users can now install any extension in the Firefox browser that they choose, without approval, creating a security risk.

When checking in about:policies, there is a policy error: Unable to parse JSON for ExtensionSettings. We have checked with Microsoft Intune support and they verified that the policy looks to be configured and targeted correctly.

Here is a snippet of our JSON, this is a test policy where microsoft support had us remove "about:addons" from the 'install sources'. Both test and production policies are not working. 

<enabled/>
<data id="ExtensionSettings" value='
{
    "*": {
        "blocked_install_message": "Contact Service Line",
        "install_sources": ["https://addons.mozilla.org/*"],

        "allowed_types": ["extension"]

    "jid1-93WyvpgvxzGATw@jetpack": {

    },

Is this a bug? Or something wrong with our configuration? Has firefox changed the requirements of the extensionsettings OMA-URI?

Thanks for any help in advance.

Your JSON code ends with e comma (,) and is missing the closing curly bracket (})

OK, I missed that you posted a snippet.

I've moved the thread to Firefox for Enterprise since this is about Intune

Thank you for moving the thread. Am I responding in the correct place?

I am also receiving the error in the screenshot below when navigating to about:policies in firefox browser and selecting 'errors'.

Here is the complete JSON:

You need to remove this line: `` 

      "install_sources": ["about:addons","https://addons.mozilla.org/*"],

```

I am having a similar issue but in my case it has never worked since I am onboarding the browser at this time. Can someone take a look at my post? https://support.mozilla.org/en-US/questions/1403897
