How to Add preferences to Firefox through Windows Server Group Policy

Hi everyone. I have installed Firefox on all windows 10 workstations and I have also installed latest Firefox Group Policy ADMX on Server. I need to set some preferences on all Workstations. The preferences that I want to set are the ones that can be found in about:config.

But the problem is that only some of these preferences exist in Group Policy by default and it says "deprecated". I know that I can add additional about:config preferences in a Group Policy object called "Preferences". But no matter how I enter the format or how I change the JASON file, no preference policy is applied to Firefox in workstations. By the way when I change "Preferences" gpo in group Policy the next Policy called "Preferences (JASON on one file)" does also change. I have thoroughly searched the web and Mozilla support and have tested all suggestions but all to no avail. Can you please help me and Give me an example of how to do that? I would appreciate any answer in advance.

Hi,

We are using Firefox Enterprise on Windows Server 2016 Remote Desktop for approx 100 users.

The users need very often to create a new profile when launching FireFox, and then loose all their bookmarks.

Is there a way to manage the profiles correctly to bypass this problem ?

Thank you for your help ! Have a nice day.

During a client Audit earlier this week we were dinged on not having the option in Firefox ESR to block manually saving Addresses and Credit Cards. We have the autofill disabled however users can still manually add credit cards and addresses and this poses an issue with our call center agents handling Credit Card info. I'd like to be able to gray out the Saved Addresses and Saved Credit Card boxes so as to prevent agents from manually entering card data into it using a GPO or Registry setting that we can push and apply to all our domain PCs. Ideally, if we could add an entry to the JSON preferences in the Mozilla GPO that would gray those options out that'd be best but any option that removes the users ability to add CC info would be acceptable.

We are currently looking at devices with out-of-date Firefox versions these are listed with vulnerabilities within our environment and need to be patched to the latest version to cover those vulnerabilities.

With the volume of patching required, we want to be able to enable auto-update and allow the application to patch itself.

However, the current options via group policy don't seem to work as I've read on such threads https://bugzilla.mozilla.org/show_bug.cgi?id=1876302.

The application Autoupdate has been enabled within local group policy as a test and nothing seems to force the application to update unless a user enters the application and selects about.

Reading into how Firefox does this it doesn't seem viable to enable an auto-update feature without specifying the version it needs to upgrade to, we can currently patch to specific versions using SCCM.

Is anyone aware of a solution to this problem or another method?

Looked into calling updater.exe and the maintenance service but nothing i successful when trying to call on these.

Good afternoon,

We're currently trying to set up a Hardening Guide for Firefox ESR but are struggling with a few policies and setting wildcards.

For example, we're trying to set an origin in Cookies > Block Settings to something like "*", and we get the error "Ignoring parameter "*" - not a valid origin."

In Chrome / Edge you can set a wildcard like this: [*.]google.com for example - we receive the same error message for this.

Can you do such a thing for Firefox ESR without having to list every site you want to block?

ESR Version: 115.6.0esr (64-bit)

I am using the gpo; Computer Configuration/Policies/Administrative Templates/Mozilla/Firefox/Extensions/Extension Management

I started out simple using a template which worked.

{ "*": { "blocked_install_message": "Your Company Blocked Message", "installation_mode": "blocked" }, "uBlock0@raymondhill.net": { "installation_mode": "allowed" } }

However, when I tried to add in more allowed extensions it now longer worked and was able to install any extension.

We are currently attempting to automate our Firefox update processes. Currently we use robocopy to push out new versions on release, but ideally we'd like to use the background updater instead. We are currently on 64-bit 119.0.1, on Windows 10 Pro 22H2. We'd prefer not to switch over to ESR if at all possible. I've already reactivated the AppAutoUpdate and BackgroundAppUpdate policies, and DisableAppUpdate is disabled, but I'm still being hit with a UAC Admin prompt when I try to launch Firefox. I tried to bypass it through the registry at [HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers], with "C:\Program Files\Mozilla Firefox\firefox.exe" = "RUNASINVOKER", but that also doesn't seem to have done anything. Any and all assistance would be appreciated

We have recently enabled background updates in our organization, however I noticed that a requirement for this to work is that Firefox needs to be run with the default profile at least once after the feature is enabled. The issue we have is that not all users are actively using Firefox and therefore they are not being updated. I realize the security flaws won't be exposed if it's not in use, but management doesn't like seeing out of date browsers. Is there a way to force auto updates on all device where Firefox isn't not being used. Background updating is working for the majority of those that do use Firefox.

Also, we do have a couple of users reporting a credential prompt when updating from 119 to 119.0.1. These same users had no issues updating from 118 to 119. I have not figured out why this is happening just yet and why only for a handful of users so far. Would anyone have an idea why that is happening?

Hi,

we want to switch our Firefox configuration from file-based (policies.json) to GPO-based. We rolled out the GPO on some test clients and it worked like a charm.

But... It shows that there are some clients which need a second firefox installation for a special purpose, which is not allowed to enter the internet or update itself.

The file-base configuration can handle these to different installations with two differend policies.json files.

Is there a way to accomplish this scenario with the use of GPOs? The GPO-base configuration seems to be global for every client.

At this moment i don't see a solution for our problem. Do you see one?
