deploying firefox-add-ons via group policies doesn't work anymore after proxy-change

Hello,

I used to deploy add-ons via group policies - this worked like a charm: Firefox esr (91.11.0esr x64), ADMX-templates in Sysvol\PolicyDefinitions, Group Policies: User configuration, administrative templates, mozilla, firefox, add-ons --> install add-ons --> https://addons.mozilla.org/firefox/downloads/file/1234567/goodaddon-1.0.01.xpi

A few months ago, we had to change our network-configuration. We were using a proxy before, but our proxy had direct access to the internet. Now our proxy forwards everything to another proxy. Since about that time, add-on-deployment via gpo doesn't work anymore. It could be something else, but i suspect the proxy-change.

I tried to deploy unc-paths, internal websites and different syntaxes; none of this works:

  • http://192.168.100.10/goodaddon-1.0.01.xpi
  • http://internalwebsite/goodaddon-1.0.01.xpi
  • https://192.168.100.10/goodaddon-1.0.01.xpi
  • https://internalwebsite/goodaddon-1.0.01.xpi
  • \\192.168.100.20\netshare\goodaddon-1.0.01.xpi
  • \\internalfileserver\netshare\goodaddon-1.0.01.xpi
  • file://///192.168.100.20/netshare/goodaddon-1.0.01.xpi
  • file://///internalfileserver/netshare/goodaddon-1.0.01.xpi

As you can see I tried using internal sites, so that no proxy would be needed. And I also added these sites to the allowed add-on-installation-sites (computer configuration, same group policy). The sites are all accessible; if I enter these addresses as url, firefox can access the xpi-file.

I know how to pack add-ons into the firefox-setup-file; that still works. But first of all, firefox is already installed on most of my clients. Second, after a fresh installation of firefox with this self-created package, all add-ons are installed, but not activated. And I would like to restrict activation/deactivation of add-ons via gpo.

  1. 1 Are there other ways to deploy add-ons in a domain-network (e.g. script-based)?
  2. 2 Are there any logs where I could find out what exactly goes wrong?
  3. 3 Are there any other syntaxes I could try (group policy urls)?
  4. 4 Can anyone guess what the problem is (why it is not working anymore)?

Help would be very much appreciated.

Best regards.
