Firefox for Enterprise Isithangami Sokwesekwa

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.

I have an issue on a Mac OS Server environment with home folders. The user's login to the MAC which authenticates to the Open Directory MAC server giving home folders to the logged-on users that reside on the server and not the local workstation. Users commonly use different computers to log in. What we're finding is that the users are increasingly getting the error message that a copy of firefox is open and firefox cannot open.

Removing the lock file solves the issue.

cd ~/Library/Application\ Support/Firefox/Profiles/ cd uniqueid.default rm -rf .parentlock

Is there a way to avoid this? We have the most current version of FF installed.

I am pushing out bookmarks company-wide through Intune on users Laptops. I spoke with Microsoft support and the configuration policy is created correctly and I followed Firefox's support page in creating them. It seems that the new JSON script that tells Firefox what bookmarks is unable to parse.

Anyone know if Firefox had an update that prevents intune from sending the JSON file?

Error message given through firefox.

"Unable to parse JSON for ManagedBookmarks"

Hi,

I deployed the last Firefox ESR update and I just found about this new feature : https://support.mozilla.org/en-US/kb/manage-downloads-preferences-using-downloads-menu

So files are now downloaded and users are no longer prompted for what to do. My question is can we change this to "Ask whether to open or save files" using policies.json?

Kind regards,

Hello, in Firefox browser, my organization has always blocked all extensions except for ones we allow through OMA-URI ./Device/Vendor/MSFT/Policy/Config/Firefox~Policy~firefox~Extensions/ExtensionSettings.

About a month ago this stopped working and our end users can now install any extension in the Firefox browser that they choose, without approval, creating a security risk.

When checking in about:policies, there is a policy error: Unable to parse JSON for ExtensionSettings. We have checked with Microsoft Intune support and they verified that the policy looks to be configured and targeted correctly.

Here is a snippet of our JSON, this is a test policy where microsoft support had us remove "about:addons" from the 'install sources'. Both test and production policies are not working.

<enabled/>
<data id="ExtensionSettings" value='
{
    "*": {
        "blocked_install_message": "Contact Service Line",
        "install_sources": ["https://addons.mozilla.org/*"],
        "installation_mode": "blocked",
        "allowed_types": ["extension"]
    },
    "cloudmetering@snowsoftware.com": {

    },

Is this a bug? Or something wrong with our configuration? Has firefox changed the requirements of the extensionsettings OMA-URI?

Thanks for any help in advance.

Hi,

I've been struggling for a week to try and get our extensions managed in Firefox. Firstly I tried doing it in Intune through the Extension Management setting in the ADMX however that wouldn't work as it couldn't parse the JSON. Then I've tried using the OMA-URI ./Device/Vendor/MSFT/Policy/Config/Firefox~Policy~firefox~Extensions/ExtensionSettings

I'm now getting a straight up error in Intune -2016281112 (0x87d1fde8). I've followed the documentation as best as I can but it still doesn't seem to work. In the Intune logs there is no record of the Config profile even being attempted. Any ideas as to what is causing this error? Here is the full code being used for the OMA-URI string:

I am currently trying to configure a very old network switch that requires Java. I have tried using the Firefox ESR (Extended Support Release) but i cannot seem to find or get the java plugin installed. I also tried downloading and installing firefox version 51.

What could i do to resolve this issue? I also tried using internet explorer but my computer refuses to install internet explorer because "it is already installed" even though it is not.

Hi,

I'm blocked because for my company i have to make a GPO that will setup the default handler for pdf files. I picked up different codes on internet but it went the same way for all of them, it didn't work. Im pretty sure that's not a GPO application issue because actually all the others setings are working perfectly.

The json code was paste on the Handlers settings as u can see in the attachement.

Hopefully that i will find help there.

Cordially.

Hi all,

I need to be able to disable the option to save Credit Card/Debit cards through group policy, has anyone got a few steps to help me through this?

Thank You

I am installing Firefox via microsoft endpoint, and deploying multi account containers with the OMA-URI policy for extensions. (this blog page is super helpful! https://securitygeneralist.blogspot.com/2019/08/auto-installing-extensions-on-firefox.html )

The extension by default has containers for Personal, Work, Banking, Shopping.

Is there a way to automatically remove that default container list as part of the install?

Even better, is there a way to create a different default containers list through Endpoint?

Thanks

We have a requirement to limit Firefox to just one internal website. Other browsers should have unlimited access, so we do not want to block websites on operating system level. I do not find any solutions in ADMX or add-ons. Please advise if anybody has a trick under the sleeves ? Thank you.

Hello, I am trying to manage Firefox Extension using "Extension Setting" via Intune. Source: https://github.com/mozilla/policy-templates/blob/master/README.md#extensionsettings I am testing below JSON for testing. <enabled/> <data id="ExtensionSettings" value=' {

 "*": {
   "blocked_install_message": "Not Allowed contact HelpDesk.",
   "install_sources": ["https://www.example.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"
 },
 "jetpack-extension@dashlane.com": {
   "installation_mode": "allowed",
   "install_url": "https://prod.extensions.dashlane.com/downloads/firefox/dashlane-latest-fx.xpi"
 }

}'/>

When deployed to test devices, all extension previously installed get removed and Ublock get installed, seem like working as intended but when I try to install any "Allowed" I get the block installed message. I see no error in "about:policies". I don't know where else to look for why its getting blocked?

Any help will be much appreciated.

This might be a simple question. Does Firefox ESR still supports NTLM v1 ? Can we still add the value "network.negotiate-auth.delegation-uris" in preference. Does that enabled NTLM v1. Is there any document or release notes that states Firefox is disabling this setting from Firefox 78 and later. Some how I am not able to find it in release notes.

We try to deploy Extension Management Settings via GPO.

Goal is to allow only whitelisted extensions, but don't block themes, dictionaries and locales.

Below find the JSON-settings deployed to the client, which should allow all themes and whitelisted extensions. Unfortunately this blocks everything except whitelisted IDs. See example screenshot with error-message, when trying to install a theme. We don't want to whitelist locales or themes, they should be still allowed for installation.

What I'm doing wrong? - Thanks for your feedback.

We're exploring the possibility of implementing a mass update for Firefox through backend management, leveraging PowerShell scripts or any applicable method that can streamline the update process for our users.

Additionally, we've encountered instances where users have installed Firefox via local profiles, posing challenges for centralized updates. I'd appreciate any insights or guidance on how we can address this issue effectively to ensure these installations align with our centralized management approach.

I would like to hide the menu button located at the top right (the three lines button) or hide the access to the firefox settings (about:preferences) but I cannot find any GPO to do this. How can I hide this button?

Thanks in advance

We are looking to mass deploy Firefox x64 for Windows to all staff in our organization, using SCCM. I know you can set a default home page in mozilla.cfg for all users, including future users who don't yet have a profile on the computer Firefox is installed on. Is there a similar option so I can configure Firefox to always show the menu bar for all users? Preferably, another line I can add to mozilla.cfg so that I can easily copy that to all our machines? Thanks.

Dear Team, Our application is accessible on Firefox v101.0.1. But recently we have upgraded our desktops with Firefox v112.0.1. The same application accessible on Firefox 101.0.1 is not able to accessible on v112.0.1.

The error code we could see on browser is SEC_ERROR+PKCS11_GENERAL_ERROR. We have already raised a case with HTTP support team but they have suggested to check at browser level. We had also collected traces from firefox but unable to upload the same. Kindly help here at the earliest. Thanks, Shruti Fegade

I am wondering if I can get some help configuring some GPO for Firefox on our new domain we are building. I want to be able to block private browsing as well as I was wondering if there is an option to force firefox to sign in with certain accounts only so we can monitor students as we are a school district
