Fóram Tacaíochta Firefox for Enterprise

We are currently looking at devices with out-of-date Firefox versions these are listed with vulnerabilities within our environment and need to be patched to the latest version to cover those vulnerabilities.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

Hello, from Terminal Servers, it is not possible to browse the Internet via FortiGate's explicit proxy from the Firefox browser, while there is no problem with Chrome or Edge. When the user tries to browse external sites, the proxy sends the error page "You need to authenticate to use this service". It seems that Firefox does not pass user authentication to FortiGate. The proxy authenticates users per session via Kerberos tickets.

Firefox version: 115.5.0esr

I also performed the following settings to pass the Kerberos ticket to the proxy without success: https://people.redhat.com/mikeb/negotiate/

I also noticed that it is not possible to change the "network.negotiate-auth.allow-proxies" setting from "false" to "true." Is this my problem? Is it normal that it cannot be changed?

Attached are the settings.

Thank you in advance.

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

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.

Hello,

I am trying to create a management policy for extensions where all themes are allowed, some extensions are force installed, other specified ones are allowed, and anything else is blocked. I have been scouring the web looking for samples and I just can't get it to work as intended. Here is a sample of what I have written.

{ "*": { "blocked_install_message": "IT has blocked the installation of UNAPPROVED add-ons. Please contact the IT Service Desk to request approval.", "install_sources": "https://addons.mozilla.org/*", "allowed_types": ["theme","extension"] }, "plugin@okta.com": { "installation_mode": "force_installed", "install_url": "https://addons.mozilla.org/firefox/downloads/file/3601147/okta_browser_plugin.xpi" }, "support@lastpass.com": { "installation_mode": "force_installed", "install_url": "https://addons.mozilla.org/firefox/downloads/latest/lastpass-password-manager/latest.xpi" }, "developer@zoom.us": { "installation_mode": "allowed", "install_url": "https://addons.mozilla.org/firefox/downloads/file/4212428/zoom_new_scheduler-2.1.52.xpi" }, "info@katalon.com": { "installation_mode": "allowed", "install_url": "https://addons.mozilla.org/firefox/downloads/file/3826743/katalon_automation_record-5.5.3.xpi" } }

In this current state, I am allowed to install themes, I get the forced installs, but I can install ANY extension. I don't want that.

If I modify the blocking section with [ "installation_mode": "blocked", ], then I only get the force installed plugins and I can't do anything else. It even removes any previously installed themes or plugins not explicitly forced in. The allowed plugins can't be installed either.

I have also tried it without the "extensions" allowed_type but the result did not change. To recap, I need to block any extensions not explicitly pushed or allowed. Would anyone be able to assist and point out what I may be missing please?

~Regards

Dear Everyone, Facing issue with deploying Configuration Profile for Extension Settings via Intune. Tried ADMX imported template with adding there "block all extensions" and allow certain ones. Worked perfect in Jamf, for Intune failing all time. We are using Firefox v.121, policies are for v.120, but I am in doubt that this is the issue. Can someone review and let me know if there any issue or may be changes? Using latest instructions https://mozilla.github.io/policy-templates/#extensionsettings Also here is my OMA, very easy.

OMA used ./Device/Vendor/MSFT/Policy/Config/Firefox~Policy~firefox~Extensions/ExtensionSettings

Value(string):

<enabled/> <data id="ExtensionSettings" value=' {

 "*": {
   "blocked_install_message": "Security Test",
   "installation_mode": "blocked",
   "allowed_types": ["extension"]

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.

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.

Attached image of our configuration profile for Pocket.

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

im tryin to instal firefox in a firm users are non admins, and i distributing from a network server made a json file with som changes and on my test machine is lookin good but on a computer in the firm is startin to act funny creatin "Firefox Privat surfning.lnk" in "C:\Users\User\AppData\Roaming\Microsoft\Windows\Start Menu\Programs" dont wont that changing my homepage settings showing "https://www.mozilla.org/en-US/privacy/firefox/ " dont want that how can i fix that try to google but no help there or is it another installer for enterprises? tryed this "https://www.mozilla.org/en-US/firefox/enterprise/#download" no diffrent

I am trying to reach an internal company website (www.gqma.drw), with a certificate chain rooted in a company certificate authority. This works fine in Chrome, and worked in Firefox on my previous computer. But i recently got a new machine, and something somewhere is not quite right. I get an error message looking like this (between the ~~~s):

~~~ Someone could be trying to impersonate the site and you should not continue.

Web sites prove their identity via certificates. Firefox does not trust www.gqma.drw because its certificate issuer is unknown, the certificate is self-signed, or the server is not sending the correct intermediate certificates.

Error code: SEC_ERROR_UNKNOWN_ISSUER

If i click on the error code, i get these details:

If i click 'View Certificate', i get a chain of three certificates:

1. Subject common name = *.gqma.drw, issuer common name = SSDNS CA, subject key ID = BE:EC:EA:22:CD:4E:D6:2A:07:4F:7A:85:FA:89:52:67:77:43:B1:E1
2. Subject common name = SSDNS CA, issuer common name = ISS Root CA, subject key ID = 8C:60:FD:78:C7:B3:FD:59:0B:73:99:E5:36:48:3F:53:A7:41:82:65
3. Subject common name = ISS Root CA, issuer common name = SS Root CA, subject key ID = 80:DD:C6:A2:AC:82:4F:FE:8A:19:2E:AA:EA:F8:BF:61:48:DC:31:73

If i go to Settings > Privacy & Security > View Certificates > Authorities, i can find both the SSDNS CA and ISS Root CA certificates. As far as i can tell, they are identical - i can open the certificate from 'View Certificate' and the corresponding one from the certificate manager and flip between tabs, and all the details are the same.

I am using Firefox 120.0, via a flatpak, on Ubuntu 22. I have given the flatpak access to /etc/ssl/certs, where my company's internal CA certificates are located.

To me, this seems like it should all work. The server has a certificate signed by an internal CA, which is signed by another internal CA, and both those internal CA certificates are in my certificate manager. So what is going wrong? Is there any way i can debug this?

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,

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.

I'm setting up addon installation through `policy.json`. Below is an example. I am wondering howto configure addons thus installed using the same file. Is it possible? If yes: where to find addon-specific keys/options? As an example: when providing below `policy.json`, starting any fresh firefox profile/installation produces the dialog "Startpage.com - Private Search Engine would like to change your default search engine from Google to Startpage.com - English. Is that OK?", followed by yes/no buttons. I would like to be able to just make the addon do so forgoing the dialog.

Thanks for any pointers.

Hi, I have a domain network that use an app open it in mozilla firefox.when we want to print a page the url address of app print with page in top and bottom of the page. 1- i want that url dont print with it page 2- how i distribute this config to all clients with group policy? Note: when i changed the margin options that url would be removed from print page.but i want do this for all page and clients.

Hello,

I used to deploy add-ons via group policies - this worked like a charm: Firefox esr (91.11.0esr x64), ADMX-templates in Sysvol\PolicyDefinitions, Group Policies: User configuration, administrative templates, mozilla, firefox, add-ons --> install add-ons --> https://addons.mozilla.org/firefox/downloads/file/1234567/goodaddon-1.0.01.xpi

A few months ago, we had to change our network-configuration. We were using a proxy before, but our proxy had direct access to the internet. Now our proxy forwards everything to another proxy. Since about that time, add-on-deployment via gpo doesn't work anymore. It could be something else, but i suspect the proxy-change.

I tried to deploy unc-paths, internal websites and different syntaxes; none of this works:

• http://192.168.100.10/goodaddon-1.0.01.xpi
• http://internalwebsite/goodaddon-1.0.01.xpi
• https://192.168.100.10/goodaddon-1.0.01.xpi
• https://internalwebsite/goodaddon-1.0.01.xpi
• \\192.168.100.20\netshare\goodaddon-1.0.01.xpi
• \\internalfileserver\netshare\goodaddon-1.0.01.xpi
• file://///192.168.100.20/netshare/goodaddon-1.0.01.xpi
• file://///internalfileserver/netshare/goodaddon-1.0.01.xpi

As you can see I tried using internal sites, so that no proxy would be needed. And I also added these sites to the allowed add-on-installation-sites (computer configuration, same group policy). The sites are all accessible; if I enter these addresses as url, firefox can access the xpi-file.

I know how to pack add-ons into the firefox-setup-file; that still works. But first of all, firefox is already installed on most of my clients. Second, after a fresh installation of firefox with this self-created package, all add-ons are installed, but not activated. And I would like to restrict activation/deactivation of add-ons via gpo.

1. 1 Are there other ways to deploy add-ons in a domain-network (e.g. script-based)?
2. 2 Are there any logs where I could find out what exactly goes wrong?
3. 3 Are there any other syntaxes I could try (group policy urls)?
4. 4 Can anyone guess what the problem is (why it is not working anymore)?

Help would be very much appreciated.

Best regards.

Hi

  Anyone experiencing an issue with Firefox 91 ESR on Win10 with blocking downloads?  We have the desktop blocked with controlled folder access and a plugin loaded which stops downloads of most file types, but when clicked on, the box appears to save the file after regardless.  The user cannot select a file location, but if they just click save it saves to the desktop anyway.  Cannot seem to stop firefox doing this. Anyone know a fix ?

Thanks,

      Jon Dickens
