Hello!

I manage our browser configuration for our enterprise. We use group policy to restrict browser addons until they clear our internal security review.

I'm looking for a way to allow specific addons using group policy, while generally blocking everything else.

I've found the setting to enforce the installation of addons, but we'd like to avoid forcing every addon to install on every system as there would be overlap between things like password managers and such.

Is there a way to accomplish this?

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?

Unattended software (kiosk) here.

Sometimes (so rarely that I cannot reproduce in dev) the client sees this error screen: "Firefox closed unexpectedly while starting..." (see image in attachment)

Sometimes when rebooting the error goes away and Firefox starts normally.

Sometimes even when rebooting the system - this vertical error screen appears, and one solution is to reinstall Firefox, but I'd like not to (if not necessary) or at least programmatically detect the issue and perform the needed actions.

QUESTIONS: How to programmatically detect (bash i.e.) that this error window is present and get rid of it properly? Or, how to (for debugging) force that screen to appear (to force that broken state)?

PS: I'm running Firefox using:

nohup firefox -P ff_custom_profile -new-instance -private-window -kiosk "$url" > /dev/null 2>&1 &

Thank you for any assistance or insight

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.

Issue with Blocking Websites in Mozilla Firefox via Group Policy

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.

Welcome, We are implementing redirected folders in our company via Widnows Server. We are also redirecting the Appdata folder. We have offline mode enabled which means that the folders are synchronised every 5 minutes. The synchronised Appdata folder has a Firefox profile which causes a lot of conflicts. Every time the folder is synced there are conflicts like "Both versions have been updated since the last sync" or "Cannot sync now. Try again". I attach a screen shot of how much of this there is. No other applications cause such errors. Only Firefox blocks us from a large deployment. If the problem cannot be resolved we will be forced to abandon the FireFox browser altogether. Has anyone had a similar problem?

Attempting to disable FF Password manager completely for my org via a plist.

Currently have the password manager itself disabled but can't figure out how to disable the Auto-fill settings with previously saved passwords prior to the password manager being disabled?

Is this possible? Or is this disabled already when the password manager itself is disabled?

Currently have this set via a plist:

Hi there,

We are currently utilizing Windows Server 2019 as our development server. To maintain security protocols, we have implemented a Group Policy to block internet access on this server. Initially, this configuration successfully restricted internet access on all browsers, including Firefox. However, recently we encountered an issue where internet access became available solely through the Firefox browser, posing a significant data security risk.

Upon investigation, we discovered that Firefox allows users to modify proxy settings, effectively bypassing our Group Policy restrictions. Unlike other browsers, Firefox permits users to adjust proxy settings without sufficient rights, thus overriding our established restrictions.

To mitigate this issue, we require guidance on enforcing Group Policy settings within Firefox to prevent unauthorized alterations to proxy settings and ensure internet access remains restricted. It's important to note that Firefox is exclusively utilized for development purposes on our server.

Your assistance in resolving this matter would be greatly appreciated.

Regards, Hiten

I was able to create a plist file for macs, and it was "deployed successfully" according to Intune, but no changes actually happened on my test machines.

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.

I am writing from an enterprise environment and I have been directed to the community page by Mozilla support to seek answers. This approach seems somewhat unreasonable for an enterprise setting and it has led me to consider discontinuing their product within our organization. I had requested support to send me a copy of my previous correspondence as I had forgotten some details, but this request was ignored, which is disappointing.

I am skeptical about receiving the help or answers I need here. If there is a more direct line to Mozilla support, I would greatly appreciate being redirected there.

We are currently using Firefox 121.0 and are attempting to implement the Applied Epic extension. I have updated the ADMX policy.

Originally, the reg key flip I created did work but something has changed since then. See screenshot of this. I followed the guide provided at https://github.com/mozilla/policy-templates/blob/v5.5/docs/index.md, which instructed me to place the registry key in Software\Policies\Mozilla\Firefox\Extensions\Install\1. However, the guide did not specify whether this should be in HKLM or HKCU. I tried this instead, and it did not work.

I also attempted to implement the extension via GPO, but this was unsuccessful. I tried the new Extension Management system as well, but to no avail.

Here is the JSON configuration I used: {

 "AppliedEpicExtension@gmail.com": {
   "installation_mode": "force_installed",
   "install_url": "https://addons.mozilla.org/firefox/downloads/file/4143256/applied_epic_extension-3.16.3.xpi"
 }

}

Despite following the guide and trying multiple methods, none of the options seem to work. I would appreciate any guidance on what I might be doing wrong.
