Hello community :)

hope everybody is doing well. I´m coming here with with asking for a help.

I´m managing browsers (Google Chrome, MS Edge and Firefox) in my company via GPOs. What we´ve been dealing with since 135 version came up is having the "Did Not Connect: Potential Security Issue error page , Error insufficient cert transparency" while visiting our internal resources.

Despite of having the security.pki.certificate_transparency.disable_for_spki_hashes set up -> main three certificate hashes are correctly added, basically copying the setup from Chromium browsers , where everything works as expected , Firefox is not.

The only way how to make it work is via security.pki.certificate_transparency.disable_for_hosts , which is , of course, not desirable , because of the security risks.

Does anyone face the same issues ?

Thank you very much ya´ll

Hello, Mozilla community.

I am trying to configure a Firefox ESR installation so that every new user on a computer automatically receives a visual customization (a logo change on about:home) through userChrome.css and userContent.css files.

My goal is to do this without using Group Policy (GPO) or logon scripts, by only modifying the files in the Firefox installation folder.

Environment:

Firefox Version: Firefox ESR 140.3.0esr

Operating System: Windows 11 Pro

Context: Standalone machine, managed without Active Directory.

My Question:

Is this method of deploying a default profile via installation files (defaults/profile or distribution.ini) still supported in recent versions of Firefox ESR?

Is there an additional step or configuration I am missing for Firefox to recognize and use the bundled profile when creating a user's first profile?

Is there any policy in policies.json that could be interfering or that is required to enable this behavior?

Thank you very much for your help and your time.

Dear Agent, My computer has been updated to Windows 11 from Windows 10. The Firefox profile settings has not changed from Windows 10 to Windows 11. How can I edit or update to Windows 11 in my Firefox profile?

Regards,

In /Library/Preferences/org.mozilla.firefox.plist:

``` <plist version="1.0"> <dict> <key>EnterprisePoliciesEnabled</key> <true /> <key>ExtensionSettings</key> <dict> <key>cloudmetering@snowsoftware.com</key> <dict> <key>install_url</key> <string>https://raw.githubusercontent.com/SnowSoftware/agent-firefox-extension/refs/heads/main/cloudmetering-v1.2.3.xpi</string> <key>installation_mode</key> <string>force_installed</string> </dict> </dict> </dict> </plist>```

In about:policies: {"cloudmetering@snowsoftware.com":{"installation_mode":"blocked","install_url":"https://raw.githubusercontent.com/SnowSoftware/agent-firefox-extension/refs/heads/main/cloudmetering-v1.2.3.xpi"}}

The plist file did read "blocked" at one point, but it no longer does. Why isn't firefox picking up the new value from the plist file? Restarting/refresing FF has not helped so far.

I have a few questions regarding the auto-update policy of extensions installed via ExtensionSettings with the force_installed installation mode.

1. Can the extension receive auto-updates just like extensions installed through normal means? (e.g. extensions installed from https://addons.mozilla.org)
2. If so, will the user be notified when the extension requests new permissions?

Greetings!

I am using the firefox enterprise version and I have noticed an issue that the browser does not capture mouse events when the pointer is at rightmost edge of the firefox window. For example, on this website near the edge the pointer would initially focus on the scroll bar and then lose focus at the edge (see attached images).

This issue does not persist on x11, and only seems to exist on wayland. It also exists on other flavours of firefox on wayland.

If more information is required, feel free to send me a ping.

I'm trying to get the Enterprise Release Notes for Firefox 148 and 149. They seem to be the only ones missing from 141 to 151 inclusive. It appears the URL for the notes is in the format https://support.mozilla.org/en-US/kb/firefox-enterprise-###-release-notes/, where ### is the version. For these two versions, I get a "Page Not Found" error.

I have tried finding them through the Firefox Release Calendar (https://whattrainisitnow.com/calendar/). If you click on the link to expand previous releases and then click on a release version number, the page that comes up has links to the three different versions of release notes. Enterprise shows a link for the two missing versions in the same format as I have noted above.

I have also tried https://support.mozilla.org/en-US/products/firefox-enterprise/whats-new-firefox-enterprise and it lists quite a few versions but 148 and 149 are missing in action.

Trying to block www.share365.net but it's not working

Le 05 novembre 2024 Bonjour, Je ne parviens pas à faire la mise à jour FireFox. J'utilise un MAC OS X version 10.9.5 Processeur 2,7GHz Intel Core 15 Mémoire 8 Go 1600 MH DDR3 MERCI de bien vouloir me répondre en Français. Bonne journée. Cordialement.

I have recently needed to update my motherboard, and the workshop put my C: and D: drives into an old second-hand motherboard they had. I have now checked Firefox - which was on my C: drive, and it works with all my old bookmarks. However I seem to now be part of an 'Enterprise', which I do not want. How do I get rid of my involvement with an Enterprise within Firefox? Thanks for your help. Kanga85

I am having the same issue as this other user here: https://www.reddit.com/r/sysadmin/comments/17wvuwh/help_pinning_extension_in_firefox_with_gpo/

Preliminaries -- Initially (before trying to force-pin), I had these GPOs enabled:

Extensions to Install -> https://addons.mozilla.org/firefox/downloads/file/4410896/bitwarden_password_manager-2024.12.4.xpi

Prevent extensions from being disabled or removed ->

• {446900e4-71c2-419f-a6a7-df9c091e268b}
• {3f6129fb-6c55-4452-ab6f-7c109b2301df}
• https://addons.mozilla.org/firefox/downloads/file/4410896/bitwarden_password_manager-2024.12.4.xpi

(Those GPOs above all work.)

What I'm trying to do: Force-pin Bitwarden.

I believe I've followed the documentation correctly (except for not including a "*" case): https://mozilla.github.io/policy-templates/#extensionsettings

I've enabled this GPO with this value:

Extension Management ->

{

 "{446900e4-71c2-419f-a6a7-df9c091e268b}": {
   "default_area": "navbar"
 }

}

After running various "GPUpdate"s and whatnot, the option to uncheck "Pin to toolbar" is still available to click.

I've verified in "about:policies#active" that the JSON item appears next to "ExtensionSettings" and that there are no errors listed in the "Errors" tab.

I've also verified that it appears in the correct location in the Registry.

Since another user had the same issue (Reddit link above), I figured it'd be a good idea to check in with y'all to see if we are missing something.

Thanks for your help!

Hi all,

For quite a while I'm working together with others on a voluntary base (nobody gets money) as members of a computer-club, a charitable NGO and NPO (in German: gemeinnütziger Verein) for seniors in order to bring them closer to the use of digital devices and media. It's not only teaching, but administrating the hard- and software as well.

I can remember that it was possible in former versions of Firefox to include at least a script into "defaults->prefs". I think it was user.js (not sure) in the installation folder to define common preferences to be fixed, like proxi settings. It always worked well, preventing non-privileged users from making any unwanted changes. As a I found out there must have been a very similar way to include add-ons (like uBlock Origin).

Unfortunately all content I found was older than about 10 years. When trying setting up Firefox as it is now, my test system didn't care about anything I've tried.

I'm talking about > 50 Windows-PC having in average 3 user profiles each (for teaching more than 400 members). We are amateurs regarding PC administration, except some network ex-professionals. "Baking" installation media including our needs, as I already found on Mozilla's pages, seems to be beyond our abilities as well as distributing a fitting profile (we don't have a MS-server), not speaking about Group Policies.

Is there any usable guideline for people like us? Today, each FF-installation looks different and I would like to unify this as easy as possible.

We have Firefox deployed and managed through Intune/Endpoint and all works well but every device has an error with this line of the policy:

UserMessaging_FirefoxLabs [./Device/Vendor/MSFT/Policy/Config/Firefox~Policy~firefox~UserMessaging/UserMessaging_FirefoxLabs] STATE Error SOURCE PROFILES Source Profile Mozilla_Firefox_Configuration ERROR CODE 0x87d1fde8

The error code is the same on all devices and is the only one present in on each device config.

Does anyone have any idea what the issue and resolution would be?

Thanks, Matt

I wanna thx for having Mozilla Firefox and i wanna ask about products for example with commercial versions but available for non profit organization in eastern EU area with social background. Im ask because afraid from local little old soft/dev gave as gift decade ago vs "confusing" logs etc?

Hello,

Our organization is attempting to implement a Conditional Access policy that restricts access to certain websites to Intune joined devices only. The error message mentions that I need to enable a setting from within Firefox called Windows SSO, mentioned here: https://support.mozilla.org/en-US/kb/windows-sso. This setting is already enabled and I am still getting an error.

Is there anything else that could be causing this?

Hello. I know how to define a server certificate exception to avoid browser warnings in case of certificate issue with a website (see attachment). However, I'd like to apply that exception for all users with access to my machine using a GPO (for user or local machine). This is also a requirement in my work where many users run Firefox from a server and the face browser warnings all the time (related to self-signed certificates) so it would be great to apply an exception for all users through a GPO specifying the self-signed certificate warning we want Firefox to ignore. Thanks.

Hello,

We are trying to automate updating Firefox ESR from 32bit to 64bit. There seems to be an issue with getting user's profiles to properly migrate for ESR. If we do a plain 32bit uninstall and 64bit installation, a new "default-esr-1" profile gets created (which is expected behavior from these Mozilla docs for new installs). But, when we set the MOZ_LEGACY_PROFILES=1 policy, this reverts to using the "default" profile instead of "default-esr" profile that was previously in use.

Are there any known ways around this which does not require user intervention to manually change back to the "default-esr" profile?

Thank you
