Firefox for Enterprise Community Forum

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.

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.

Hi, I would like to migrate my 5000 users over onto FF. One of the requirements is to preload bookmarks for these users, something we can do with Chrome already. We are running on Windows devices and use an ADMX and an XML (listing the bookmarks and folders) to push this policy via InTune. I can't find any means of replicating it in FF... is it possible?

the settings ExtessionSettings does not show up to be able to modify even tho it is on the ADMX file (5.11)? Should I use the older Extensions policies? I want to install and pin an extension from the store.

Hi, I would like to implement GPO settings for Firefox, and would like to review the list of the policies with description (explanation of what the policy is about and what happens if its enabled or disabled) on a table or excel format. Is there a site or page that will give me that list?

Seems to be new in 122.0 because i never received that before. It asks if you want to open links with Firefox and if you do, it sets file associations for htm / html and things like that. However in a company environment i want to supress that notification

Is there a way to trigger a Firefox browser update through command line or script? I need to trigger an update across a few hundered computers and I can do this, but through command line or script automation. What is the command line syntax to do this, if there is any?

Thank you for your help

Hello,

We have a client using Azure Virtual Desktops. Most of the users prefer to use Firefox. We are having an issue that anytime we update Firefox and reimage the virtual hosts. When the users login they get a new Firefox profile. We have to remote in and copy their old profile data to the new profile.

Is there a better way for us to handle Firefox and profiling in and Azure Virtual Desktop deployment?

Dear Forum,

Maybe this has been already asked but i keep getting the quite opposite when searching.

is there a way that i can save passwords, for autofill purposes, for specific websites in Firefox using GPO?.

I have 4 computers, that are currently deployed with Firefox and all 4 should be able to login to a specific website with a given username and password. I would like to set the username and password for them stored in the Firefox password manager and let it autofill it for them when going to the given website.

Or should i do this using the created shortcut they received, deployed to their systems using GPO?

Thank you in advanced.

We followed the links below to block internet access in Firefox browser:

https://www.youtube.com/watch?v=fAGYYX5hYb8 https://github.com/mozilla/policy-templates/releases

We downloaded the ADMX and ADML files. Using these files, we were able to locate Mozilla Firefox in Group Policy Management and successfully block all websites in the Firefox browser using the pattern :///*.

However, we encountered an issue with exceptions. We do not wish to block certain websites, including localhost. We attempted to use the "Exceptions to block websites" option, providing values such as ://msn.com/ to exclude specific sites. Unfortunately, this approach did not work as intended. For instance, msn.com is one of the websites we want to allow, among others and also localhost.

We require assistance with the following issue: "Exceptions to block websites" is not functioning properly within the group policy of Mozilla Firefox.

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

Hi all

I like to enforce the following setting "Require device sign in to fill and mange passwords" in the mozilla.cfg but I couldn't find the setting in about:config.

Can anyone help?

Firefox is used on Windows 11 Enterprise. There is a firefox.cfg in the installation directory (and an autoconfig.js in the ./defaults/pref sub-directory). The firefox.cfg targets an autoconfigfile.js. This setup is recommended here: [firefox using autoconfig"]

1. In the support article´s example, the firefox.cfg uses a pref(); expression. Is it possible to use a lockPref(); expression instead?
2. What is the result of either using pref(); expressions or user_pref(); expressions in the remoted autoconfigfile.js? Are both of them possible, especially while the firefox.cfg uses lockPref(); expressions instead of pref();?

I hope that somesone can help with one of these questions. Thanks a lot!

Hi,

I already have the admx and adml templates installed on my gpo. I would like to control or prevent the install of vpn extensions on the firefox browser.

Specifically I would like to prevent the install of all vpn extensions to the firefox browser for the users in my company. I would like them to download and install other extensions. How could I do this through modifying the json file in the extensions folder of the firefox template in my gpo.

Thanks in advance, Floyd,

Does anyone possess expertise in executing a forced update for Firefox within the user's profile directory located at "AppData\Local\Mozilla Firefox"? It would be advantageous to employ a PowerShell script for rectifying this issue. It appears that certain users are not frequently opening Firefox, thus impeding the automatic update process.

Hi there,

We would like to disable ECH on our browsers as it is interfering with our Anti-virus Website blocks. I have identified the settings that need to be changed in about:config and was able to configure 2 of them to be controlled via a registry key but was not able to for another 3 as their keys should be placed in a different Key in the registry. I have searched all over but cannot identify the name for this Key.

The settings I need to manage are in the image. I was able to configure the settings beginning with network.dns but I am not sure how to manage the settings beginning with security.tls.ech

Any help would be much appreciated

Is there any parameter or group policy similar to Chrome "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome\AutoSelectCertificateForUrls]", as we implemented application with Certificate sign-in, it pop-up every time when navigating to different on-prem servers, we enabled Group policy for MSEdge & Chrome, but need to do same for Mozilla Firefox.

I need expert advice on this subject matter.
