How to block addon-installation but allow "build-in" addon openh264 ?
in our company we use firefox esr 78.2 and have blocked the installation of add-ons with our gpo-settings. But we need the openh264-codec-plugin to work (for video conferencing). Is there a chance to only allow / whitelist the openh264-plugin, so firefox can complete this codec-installation ?
We need something like the chrome-policy ExtensionInstallWhitelist: https://www.chromium.org/administrators/policy-list-3#ExtensionInstallWhitelist
thanks in advance and greetings from germany
