Firefox for Enterprise Support Forum

I would like to prevent users to navigate on the Linux system when they view a PDF and then use the Save option. The "PDFjs" policy enables or disables the PDF Viewer but does not control the built-in PDF Viewer menus.

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.

I'm setting up addon installation through `policy.json`. Below is an example. I am wondering howto configure addons thus installed using the same file. Is it possible? If yes: where to find addon-specific keys/options? As an example: when providing below `policy.json`, starting any fresh firefox profile/installation produces the dialog "Startpage.com - Private Search Engine would like to change your default search engine from Google to Startpage.com - English. Is that OK?", followed by yes/no buttons. I would like to be able to just make the addon do so forgoing the dialog.

Thanks for any pointers.

Hi, I am looking for a security Hardening guidelines for Firefox from Mozilla. Could you please guide me to the right direction where I can find one.

Thanks Raju

We have used Firefox in our environment for well over a year in the configuration explained here: https://help.okta.com/en-us/content/topics/directory/ad-dsso-configure-browsers.htm

OKTA is our Identity provider to do Single Sign on to our SaaS applications.

today when version 118 rolled out, this functionality stopped working. Can you help me to get this working again. Chrome and Edge are not affected, so we have options, but we would really like to use Firefox.

Thanks so much for your help

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.

Thanks! -Doug

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?

Thank you.

Hello, I am trying to manage extensions in my organization. What would be the best way to block all extensions by default and allow only certain specific extensions?

I am following the Mac OS Extension Settings Policy and adding this to a configuration profile, but I am not sure how to manipulate it to suit my needs.

What would be the best way to go about this, and what would the plist file look like?

Thanks!

Dears, Based on your documentation on https://github.com/mozilla/policy-templates/blob/master/README.md#extensionsettings I am not able to successfully deliver setting to firefox app via Intune OMA-URI. Can you check this on your side and help?

I have one extension to be installed on the enterprise network machines. There are host permissions required to access All websites data. How can I, as an Admin, enable this host permissions for the installation ?

Hello, I want to increase my productivity and add Unhook: Remove YouTube Recommended Videos Comments It hides comments and suggested videos from YouTube, or more videos, but unfortunately I can delete or deactivate it easily. I want to prevent it permanently, and also add Cold Turkey Blocker I want to prevent myself and any user from deleting it, and then I will block access to the local group policy editor using Cold Turkey Blocker And when I do this through the local group policy editor I get an error message, please help me

When I type about:policies, I get "The Enterprise Policies service is inactive". I'm trying to validate my configuration against Firefox STIGs which require certain of these policies to be set. So what does this message actually mean? Does it mean no policies are set? Are they set somewhere else? I have Windows Server 2016. Thank you.

Is there a way to force Firefox updates within a specified time window via group policy? The ADMX templates appear to allow enabling or disabling updates or enforcing background updates, but we are not seeing an option in Group Policy to configure a delay or time window for searching for app updates.

Hi

i need to know how to achieve the following using windows 10 registry.

1. Block Extension installations and disable existing installed extensions.

2. Allow only approved extensions so that users could install it from the store.

These settings were able to configure easily for Chrome and Edge browsers.

Thanks Muja

Hello, and good day. Some of my employees in our org have been using Mozilla as their preferred browser; however, I am having difficulty deploying or managing the browser to deploy the Torii Extension/add-on.

Torii provided me with this link https://support.toriihq.com/hc/en-us/.../5148326594203-Deploy-the-Firefox-Extension to deploy the extension but still to no avail. Can someone assist me with getting this tested and deployed?

Thank you!

I work in an enterprise environment. We have certain requirements that we must maintain for our system to maintain accreditation. One of these requirements is to prevent the installation of add-ons using the policies.json file.

We are also trying to develop an extension that adds banners to each page the user interacts with. I understand this can be loaded using the process [https://support.mozilla.org/en-US/kb/deploying-firefox-with-extensions|he...] and does not have to be signed following this [https://support.mozilla.org/en-US/kb/install-system-add-ons-firefox-enter...] .

My question is, before embarking on the journey to create this web extension, can it still be installed following the enterprise process, despite being denied by default by the policies.json? Or is there a way to allow for the extension to be installed by changing the policy?

Hello. I have trying to test a GPO this week that will lock down the use of extensions. In summary we are shifting to a complete "deny all/allow by exception format".

As a reference I have been using the below article as my source on how to set this up. https://github.com/mozilla/policy-templates#extensionsettings

After reading through the article the base example they have works flawlessly. I have put this base example below.

{

 "*": {
   "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 minute I try to change it though the whole thing breaks. For context, I have tried adding 1 password as a forced installed add in, and also try placing it below under allowed. See my example below of the one where I am putting it is allowed. Any idea of what I am doing wrong?

{

 "*": {
   "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"
 },
 "*": {
   "installation_mode": "force_installed",
   "install_url": "https://addons.mozilla.org/firefox/downloads/latest/1password-x-password-manager/latest.xpi"
 }

}

Hi Dear support mozila Firefox IT team,

I need to find out if there is an option on the user's computer in the local network, how to connect to the bypass list of the Firefox browser with a hidden version. Which aims to adjust, add and modify without bothering the user to quickly organize the work. If there is an option, please send me a guide.

In our organization, we enforce through group policy to clear cookies and site data each time the browser is closed. I see there's an exception list to define certain sites that it will not clear cookies or site data. Where in group policy can this exception be set.

This option can be seen (allow) from the article here under Block cookies and site data for more than one website > Step 3 https://support.mozilla.org/en-US/kb/block-websites-storing-cookies-site-data-firefox

Thanks,
