I am deploying Mozilla Firefox using Intune. The application is deployed no problem but there is always the error in Intune portal. I was told that Mozilla Firefox has custom return codes to indicate post-installation behavior. That is why though the application itself is installed and works properly on the device, Intune portal does not know the status of the installation and gives the error. This error causes a lot of issues to the further application management. Dose any one knows what those codes are? Or maybe can point into the correct direction on how to get them. Thank you.

Hi all,

we are using Mozilla Firefox ESR in our enterprise environment.

Is there a documentation which URL's Firefox uses when (Mozilla Maintenance Service) when it tries to update his version ?

We have tried with following URL's on our Firewall:

aus.mozilla.org aus2.mozilla.org aus3.mozilla.org aus4.mozilla.org aus5.mozilla.org download.cdn.mozilla.net archive.mozilla.org ftp.mozilla.org

It is finding the new version, but when trying to download the update it fails.

Thank you for any help on this case.

Multiple banks are removing Firefox due to vulnerabilities. They have found as I have told them multiple times that there is no centralized method to ensuring firefox remains up to date. The admx files from github do set the appautoupdate and backgroundappupdate to a value of 1 to indicate updates but all PCs are at different levels from 90.0 to 95.0 and I've found that even with the auto update switch on that many pcs do not auto update due to users leaving firefox up and ignoring the restart. The autoupdate task runs only if the user is logged on and that allows users to browse with an insecure version of Firefox that can lead to data breaches. CVEs lead to threats to exploit the CVE and that leads to risk that leads to data breaches. These CVEs are tracked by the NVD and this puts security in the hands of users instead of the business and the business has decided to remove firefox from their environments due to this fact.

I know mozilla is NFP but to maintain firefox in an enterprise environment, it need a better update process such as Google Chrome and Edge Chromium.

CVE-2021-38503 CVE-2021-38504 CVE-2021-38505 CVE-2021-38506 CVE-2021-38507 CVE-2021-38508 CVE-2021-38509 CVE-2021-38510

The above are current CVEs of High risk in one environment that has decided firefox will no longer be used.

Hey! We want to use Firefox in our school. The school computers are running Windows 10 in a domain. The normal users don´t have rights to install software / updates. That's why we want to use the Mozilla Maintenance Service but it doesn´t work as expected.

After installing a clean Firefox (no old profiles, data, or anything else) it shows that there is a new version. When you click on that message you have to get through Windows UAC. With the admin it is just a "yes"-click but everyone else needs a password.

Any ideas what i can check or try to get the Mozilla Maintenance Service updating Firefox?

Thanks a lot! Nils

Thanks Mike for the description here: https://support.mozilla.org/en-US/kb/firefox-enterprise-87-release-notes by Mike Kaply

Does the following section meant that policies.json would win a conflict with a setting that is also set in GPO: The policies.json file is no longer ignored if policies are specified via GPO (Windows) or configuration profiles (macOS). The policies are combined with GPO or configuration profile taking precedence over policies.json where there are conflicts.

distributing a customized Firefox in small enterprise

Hello everyone,

I got around 50 windows clients to deal with and I wonder how to create a customized version to distribute via Kaspersky Security Center.

What I intend is to create an .msi, a folder or something to install. It should include some extensions like ublock or https-everywhere and such. I also like to have a customized theme included.

There are some ressources like AutoConfig or GPO GPO or repackaging installer. But I don't know if the procedures still work since the documents are three years old and, to be honest, I didn't manage to get anything work that way.

Isn't there a simple way to roll out Firefox in a company with some customization?

Thanks.

Since Firefox allows users to install to individual profiles, how do admins go about uninstalling it for all users silently and remotely? If all 1000 PCs have 50 users, all with Firefox installed to individual profiles, I can't imagine IT admins would have to find the appdata for each and every user and modify a script for each machine and every user. There must be a simpler way, right? An "Uninstall All" for Firefox?

Hello, I use on 90 computers Mozilla Firefox, v.89. In need to stop update and update notifications. I understand the benefits of an updated version, but I need to keep a version without updates, for a time. Update notifications confuse PC operators working on stations with limited users. Thank you.

I would like to get new security updates for Firefox, i dont have Internet connection so the updates must come in some other way.

is it possible to download updates somewhere and then place then on a share on a fileserver and then i can tell Firefox look for updates on this share instead of Internet.

I already use this technic for Windows Defender, i download the definition files and the enable a GPO that tell Defender that all updates are on a fileshare.

Can this be done in Firefox (or something similar?

Hope you understand what i am trying to achieve

What is the specific URL that is required to access auto-updates from the client? As an enterprise, we have locked down devices that have limited Internet connectivity. Our security area will not open the entire download area, so we are looking for the specific URL or web address that is needed so we can still auto-update clients. We want to move more people to Firefox, but need to get this working first.

Why does FF reset the homepage to firefox home with the latest update? We deploy our Windows based systems to hundreds of customers and count on FF to bring them to our company homepage to check for updates, documentation, etc. How can I make sure my customers systems always start on my homepage? P.S. We have hundreds of customers so going to each system is not really feasible.

Firefox for enterprise setting up with MS Intune

I am attempting to setup Mozilla for enterprise version 81.0 (x64) to deploy through Intune and update the previous versions on our client laptops. I set up Intune with the following detection rule(attached). The idea is that Intune looks for this registry key and if its not at version 81.0 it pushes out the updated MSI file. What happens so far is that when I have a older version installed such as 74.0. Intune DOESN'T push out the update. However when I completely remove Firefox within minutes Intune detects that its not installed and pushes out the current version. Therefore it would appear that the detection rule works but not as intended. A attempted to adjust the value on the detection rule with no success. The original detection rule was to detect a file inside program files\mozilla firefox. However that rule would not detect the current version installed.

Any ideas would be helpful.
