I am trying to manage Firefox extensions using a GPO using code below (Computer Configuration->Administrative Templates->Mozilla->Firefox->Extensions->Extension Management). The format below aligns with what is listed here "https://github.com/mozilla/policy-templates/blob/master/README.md#extensionsettings" and this is not working as expected. The goal is to only allow users to install the allowed extensions listed and everything else gets blocked. Please help?

Not sure if related but I also have "Extension Update" enabled

Your code has a a lot of extra lines with a closing '}'. You can try this code instead.

Software\Policies\Mozilla\Firefox\ExtensionSettings (REG_MULTI_SZ) =
{
 "*": {
    "blocked_install_message": "Your admin has blocked adding this extension.",
    "install_sources": ["about:addons","https://addons.mozilla.org/"],
    "installation_mode": "blocked",
