Firefox for Enterprise Support Forum

We downloaded the GPO Templates for AD and looking to customize Firefox.

We would like to disable Forms and Autofill: Autofill addresses Autofill credit cards

Also would like to lock down so they can't reenable if possible.

We would like to do this all through GPOs if possible. I found these in the about:config: extensions.formautofill.addresses.enabled extensions.formautofill.creditCards.enabled

But again want to do through the GPO. Is this possible?

Side note while working on GPOs, I set Exceptions for the popup blocker and they are not showing up in the browser. I also filled out to remove Search Engines but they all still appear in the browsers. These two GPO settings don't appear to be working.

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.

Version: Firefox ESR 102.9.0 (64-bit) - Windows 10 Enterprise 22H2

Customers have been complaining for about 6 months that they can no longer drag and drop email attachments from Outlook (Microsoft Office Professional Plus 2019 - Exchange) into a Help Desk formula. I tested dragging from Outlook desktop and from the web version.

Drag and Drop works when using Edge and Chrome.

This is not a major issue, since customers can use the other browsers, but since they would prefer to use Firefox, a fix would really be appreciated.  :-)

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?

Been managing bookmarks for users through Intune, but for some reason on my HP Elitebook 840 I keep getting an error "Unable to parse JSON for ManagedBookmarks" I haven't changed anything to the bookmarks before swapping to the HP laptop from a Dell 5410. I have double-checked GitHub for the proper string for bookmarks and everything looks to be correct as well as submitting a support case with Microsoft who checked it and say it is something on Firefox's side that needs fixing.

I am also constantly getting this unknown extension setting. Not sure why I have this or where I can remove it.

ExtensionSettings {"firefoxhpsureclicksecurebrowsing@bromium.com":{"installation_mode":"blocked"},"firefoxhpwolfsecurityextension@bromium.com":{"installation_mode":"blocked"}}

We have Firefox-ESR in use and we are using Applocker.

When we enable applocker dll Rule policys and start https://shaka-player-demo.appspot.com page clearkey addon crashes.

We have allowed widevinedrm.dll in applocker rule policys, and we have used Process Monitor to track which dll file / files are being "locked" but we cant seem to pinpoint it.

Where does Firefox-ESR run DRM content and which dll files are needed to run ?

What we know that it is caused by applocker DLL rule policys, when disabling it clearkey addon does not crash and drm content can be played.

Also Applocker eventlogs does not show anything related to this.

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"
 }

}

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 ?

Hi there,

we trying to restrict internet access that used Mozilla Firefox on client computers through Microsoft Intune.

We have already configured policy by uploading ADMX template & Custom OMA-URI as described in https://github.com/mozilla/policy-templates/blob/master/README.md 

We are trying to add custom allowed web sites to "WebsiteFilter" OMA-URI ./Device/Vendor/MSFT/Policy/Config/Firefox~Policy~firefox/B_WebsiteFilter_Exceptions. added web sites are not allowed. my question is what is the best way to enter URLs (I mean format) to allow list & how I can used wild card to allow all the web sites of one specific domain. eg:- microsoft

in our organisation i need several domainnames to be added in network.negotiate-auth.delegation-uris and network.negotiate-auth.trusted-uris, so that sso for some webapplications is working. some are allready in the list. when i make changes to the list, everything is working ok, but when i clos all mozilla windows and restart mozilla, the changes are gone.

We have Firefox rapid-release (not ESR) deployed on Windows 10 across our Enterprise where users do not have local Administrator privileges.

Occasionally the rapid-release updates fail to be installed, with the updater requiring Admin privileges to execute. For example, today a user's Firefox 111.0.1 was asking for elevate to update to 112.0.

The IT team user accounts also are non-admin, but we have not run into this, and judging from the lack of support tickets on this I would say most of our users are not running into this either.

Does anyone have any suggestions on how to avoid this, or troubleshoot further?

Hello

I am looking for a way to disable the QUIC protocol in Firefox by GPO. I got your latest AMDX templates but I don't see the option to modify network.http.http3.enabled.

Either an AMDX template with this option or a Registry will do the trick

Thanks

I work for the local County and we recently got a new content provider that allows for SSL Inspection (Barracuda 410) but it requires a certificate to be installed on every device to work. I am aware of Edge having a way to create a custom installer that would allow us to preinstall the proper certificate, but was wondering if Firefox had the same thing. I am also needing to know that if we push out the version of Firefox with the certificate preinstalled, would it auto import our user's data from their current install of standard Firefox?

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,

on GitHub the commands are all based on Java https://github.com/mozilla/policy-templates#preferences

Is there a list of all available registry settings? Or where do these Java options come from, where can I read them out?

Environment: Windows 10 22h2 clients, latest ESR build, Domain servers Windows 2016 or better.

So I followed the guide https://github.com/mozilla/policy-templates/blob/master/README.md#extensionsettings and tried to set up the config. We are using the latest ESR build but after the settings is applied I still dont have working extensions.

Here is the code

{
     "*": {
           "blocked_install_message": "Addon or Extension is not approved. Please submit a ticket to Help Desk if you need access to this extension.",

           "installation_mode": "allowed",
           "install_url": "https://extensions.onelog.com/extension/onelog.xpi"
     }

}

I have placed the settings in HKCU but also tried in HKLM and there has been no difference. in each case I get Unable to parse JSON for Extensionsettings when checking the about:policies section and when I look at the registry I see the REG_MULTI_SZ value but when i click on it to read it I get another error message. Cannot edit ExtensionSettings: Error reading the values contents.

I tried re-entering the code and tried not listing the install URLs and even tried only listing 1 item. I haven't been able to get past this error so any help would be greatly appreciated.

Hello,

We have a vulnerability scanner in our environment that tells us when Firefox needs to be updated. We found that in order to update it, we need to go the settings tab and then to the updates portion of the menu to initiate the update. After this we are asked to restart. Any way to avoid this entire process?

Hello,

We have set up a GPO in our Active Directory environment for the install of Firefox which works great, however since at least version 90, we have had an issue where Firefox won't uninstall automatically when removing the computer object from the security group associated with the GPO. The box is ticked to "uninstall this application when it falls out of scope of management", which works for every other GPO we have created. The computer removes the assignment of the application, but does not then remove the application as it should.

Are you aware of this issue?

Thanks.

Hello,

I am managing Firefox for a very large organization. We have several extension that we deploy using registry keys and we don't allow users to install additional addons. However, since version 102.3 I noticed some extensions that are present on the machine as .xpi files, but should not install unless a specific application is also present, are also being activated. They are enabled in the add-on manager, the information is present in the "extensions.json" and "extension-preferences.json" files. This should not happen. Is there any way to prevent the activation of these files?

Thank you!
