Looking to specify homepage, homepage button, and new tab page within Firefox on our Mac fleet.

I was able to create a plist file for macs, and it was "deployed successfully" according to Intune, but no changes actually happened on my test machines.

I've uploaded a redacted version of the used plist.

Anyone out there have any ideas?

I am writing from an enterprise environment and I have been directed to the community page by Mozilla support to seek answers. This approach seems somewhat unreasonable for an enterprise setting and it has led me to consider discontinuing their product within our organization. I had requested support to send me a copy of my previous correspondence as I had forgotten some details, but this request was ignored, which is disappointing.

I am skeptical about receiving the help or answers I need here. If there is a more direct line to Mozilla support, I would greatly appreciate being redirected there.

We are currently using Firefox 121.0 and are attempting to implement the Applied Epic extension. I have updated the ADMX policy.

Originally, the reg key flip I created did work but something has changed since then. See screenshot of this. I followed the guide provided at https://github.com/mozilla/policy-templates/blob/v5.5/docs/index.md, which instructed me to place the registry key in Software\Policies\Mozilla\Firefox\Extensions\Install\1. However, the guide did not specify whether this should be in HKLM or HKCU. I tried this instead, and it did not work.

I also attempted to implement the extension via GPO, but this was unsuccessful. I tried the new Extension Management system as well, but to no avail.

Here is the JSON configuration I used: {

 "AppliedEpicExtension@gmail.com": {
   "installation_mode": "force_installed",
   "install_url": "https://addons.mozilla.org/firefox/downloads/file/4143256/applied_epic_extension-3.16.3.xpi"
 }

}

Despite following the guide and trying multiple methods, none of the options seem to work. I would appreciate any guidance on what I might be doing wrong.

Hello,

I am trying to create a management policy for extensions where all themes are allowed, some extensions are force installed, other specified ones are allowed, and anything else is blocked. I have been scouring the web looking for samples and I just can't get it to work as intended. Here is a sample of what I have written.

{ "*": { "blocked_install_message": "IT has blocked the installation of UNAPPROVED add-ons. Please contact the IT Service Desk to request approval.", "install_sources": "https://addons.mozilla.org/*", "allowed_types": ["theme","extension"] }, "plugin@okta.com": { "installation_mode": "force_installed", "install_url": "https://addons.mozilla.org/firefox/downloads/file/3601147/okta_browser_plugin.xpi" }, "support@lastpass.com": { "installation_mode": "force_installed", "install_url": "https://addons.mozilla.org/firefox/downloads/latest/lastpass-password-manager/latest.xpi" }, "developer@zoom.us": { "installation_mode": "allowed", "install_url": "https://addons.mozilla.org/firefox/downloads/file/4212428/zoom_new_scheduler-2.1.52.xpi" }, "info@katalon.com": { "installation_mode": "allowed", "install_url": "https://addons.mozilla.org/firefox/downloads/file/3826743/katalon_automation_record-5.5.3.xpi" } }

In this current state, I am allowed to install themes, I get the forced installs, but I can install ANY extension. I don't want that.

If I modify the blocking section with [ "installation_mode": "blocked", ], then I only get the force installed plugins and I can't do anything else. It even removes any previously installed themes or plugins not explicitly forced in. The allowed plugins can't be installed either.

I have also tried it without the "extensions" allowed_type but the result did not change. To recap, I need to block any extensions not explicitly pushed or allowed. Would anyone be able to assist and point out what I may be missing please?

~Regards

We are working on implementing Firefox for Enterprise and rolling it out through Intune/Company Portal, one challenge we are encountering is that we have disabled Pocket as thoroughly as we can (followed the guide from Mozilla https://support.mozilla.org/en-US/kb/disable-or-re-enable-pocket-for-firefox) and we are still seeing requests go out to "img-getpocket.cdn.mozilla.net" we do not want Pocket available at all, we do not want queries made to those domains, is it not possible to completely eradicate Pocket?

It wouldn't be a problem but our AV solution (MDE) has a popup every time the URL is queried and blocked.

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: … (xle nububuwo)

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.

When looking at the ExtensionSettings page for Firefox or Chrome they both use an example that shows the registry key Software\Policies\Mozilla\Firefox\ExtensionSettings… (xle nububuwo)

When looking at the ExtensionSettings page for Firefox or Chrome they both use an example that shows the registry key Software\Policies\Mozilla\Firefox\ExtensionSettings (REG_MULTI_SZ) being set to a long JSON string with every extension ID and the settings for that particular ID. For example...

{

 "*": {
   "blocked_install_message": "Custom error message.",
   "install_sources": ["https://yourwebsite.com/*"],
   "installation_mode": "blocked",
   "allowed_types": ["extension"]
 },
 "uBlock0@raymondhill.net": {
   "installation_mode": "force_installed",
   "install_url": "https://addons.mozilla.org/firefox/downloads/latest/ublock-origin/latest.xpi"
 },
 "https-everywhere@eff.org": {
   "installation_mode": "allowed"
 }

}

The problem with this method is that if I am installing an extension, and I overwrite what already exists in Software\Policies\Mozilla\Firefox\ExtensionSettings then all of those other settings get removed. So even if I am a non-malicious actor and just make a mistake with my installer I can easily delete every other extension's settings. Instead what I have to do is during install I have to read the current value of Software\Policies\Mozilla\Firefox\ExtensionSettings and then insert my extension's settings into the JSON blob.

So the examples that Firefox and Chrome provides do of course work, however they do not make very much sense to me. Why would it be formatted this way since all of those are additional key/value pairs and that is exactly what the registry excels at storing. So why put all of those into a single key/value instead of breaking them into multiple?

Additionally breaking them a part into multiple key/value pairs does work! So if instead of the example above I were to split them into multiple key value pairs it works just fine!

Software\Policies\Mozilla\Firefox\ExtensionSettings

   uBlock0@raymondhill.net
       "installation_mode": "force_installed",
       "install_url": "https://addons.mozilla.org/firefox/downloads/latest/ublock-origin/latest.xpi"

So knowing that this way with multiple key/value pairs works why am I bothering to ask this question at all instead of just doing it the way that makes sense to me? Well the issue is that by breaking it up into multiple key value pairs it actually overrides the other method and makes it so that all those registry settings are ignored. So it doesn't delete them but it still leaves me with nearly the exact same problem.

While I believe "my" way is superior because it uses the registry in a more common sense route, if that is not what the majority of extension developers do then it doesn't matter and I should be conforming to the other way.

As I am typing this question up I did realize just how hard/annoying it is to properly format and make it clear and digestible what the multi key/value format of the registry would look like instead of being a JSON string. So perhaps that is the reason why all the documentation puts it all as one JSON string?

Hi All,

I am trying to block the Last Pass extension in Firefox using Intune, and the ADMX configuration setting is not working on the endpoint. I've used the templates found here

https://github.com/mozilla/policy-templates/releases / Target Extension "support@lastpass.com"

And have tried using the imported admx template as well as a single line OMA-URI.

I've worked with Microsoft, and they see the correct settings on the device as pushed out via Intune, so they said it is not on their end. Any ideas why blocking named browser extenstions is not working? I've configured a few other settings with Intune/ADMX templates and they work.

Hello,

I have a plug-in installed on multiple machines using group policy. The installation source is a link to <my_add_on.xpi>. My question is regarding the updates approach. If I replace the source file with an updated version, but keeping the name/link the same. Will Firefox automatically update the plug-in? Only found brief docs here: https://github.com/mozilla/policy-templates/blob/master/README.md#extensionsettings """

If you need to update the extension, you can change the name of the extension and it will be automatically updated. Extensions installed from file URLs will additional be updated when their internal version changes.

""" I don't point to a local file, but rather a URL. Does that make a difference. Or I'll have to provide the updates.json in the plug-in manifest that points to the latest version?
