Hi!

Using Intune, we are setting some settings in Firefox. One that is a bit troublesome is the ExtensionSettings

Currently looks like this:

{

 "*": {
   "blocked_install_message": "Blocked.",
   "installation_mode": "blocked"
 },
 "uBlock0@raymondhill.net": {
   "installation_mode": "allowed"
 },
 "addon@darkreader.org": {
   "installation_mode": "allowed"
 },
 "@react-devtools": {
   "installation_mode": "allowed"
 }

}

I get the Blocked message if I try any of the allowed extentions like uBlock, Dark Reader or React Dev Tools.

I can add that uBlock had "force_installed" (With URL since that is required for force) and that worked fine.

What do you see for ExtensionSettings in about:policies? I've found Intune can be finicky about updating the client.

This is a copy-paste from about:policies:

{"*":{"blocked_install_message":"Blocked.","install_sources":["https://addons.mozilla.org/"],"installation_mode":"blocked","allowed_types":["extension"]},"uBlock0@raymondhill.net":{"installation_mode":"allowed"},"addon@darkreader.org":{"installation_mode":"allowed"},"@react-devtools":{"installation_mode":"allowed"}}

You can see all settings here: https://pastebin.com/0JAhNQe7

Edit: Solved, had to remove the preference: extensions.blocklist.enabled:1

I just tried with your ExtensionSettings and it's working for me (those allowed, others blocked).
