Not able to deploy Languagepack Addons trough GPO - Firefox 75.0

more options

Hello,

in our environment we have different Citrix PVS Images and would like to use the same gpo for firefox for all Images.

As we live in a multilingual country, we need to distribute german and italian languagepacks for firefox. We used the firefox.cfg with the following settings to achive this goal:

lockPref("extensions.blocklist.enabled", false); lockPref("extensions.autoDisableScopes", 0); lockPref("intl.locale.requested", "");

XPI Files where copied to C:\Program Files\Mozilla Firefox\browser\extensions\sample.xpi

With the release of Firefox 73.0, sideloading is no longer possible. Adding the extension trough GPO "Extensions to Install" https://addons.mozilla.org/firefox/downloads/file/3541579/italiano_it_language_pack-75.0buildid20200403170909-fx.xpi is not the way i would like to achive this.

Documentation (https://github.com/mozilla/policy-templates#extensionsettings) isn't exactly clear how to add an extension from a local source. GPO Setting would be Software\Policies\Mozilla\Firefox\Extensions\Install\2 = "C:\Program Files\Mozilla Firefox\browser\extensions\langpack-de@firefox.mozilla.org.xpi"

Chosen solution

My recommendation would be that you put the languages in distribution/extensions (named the same as the ID which you've already indicated)

That should get you close to the same behavior you had before (only difference is that users can uninstall the language packs which you can prevent via policy)
