Intune ExtensionSettings Policy No Longer Working in Firefox
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.

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.

Hi, according to the doc it looks OK, except that the last bracket is missing.
Hi, yes followed this doc. And las bracket is not missing in actually policy, this was just a snippet.
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

You need to remove this line: ``

```

Hello, was actually just missing an additional closing bracket.
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
Hi daniel.david.white
I've moved your question to this Firefox for Enterprise forum, so please continue there.
