Firefox Enterprise Community Forum

Hi guys,

I'm trying to uninstall an extension using a GPO, but it's not working.

I've placed a GPO on the user's OU and configured the ID to be removed in the User-Part of that GPO. I previously retrieved the ID using about:debugging.

But nothing happens; the extension isn't removed. (Logoff/Logon/reboot/gpupdate /force .....)

128.11.0esr (64-Bit)

KeePassXC-Browser Extension

The GPOs for Edge and Chrome have the same function. Enter the ID there, and the extension is reliably removed.

Any suggestions? Thanks

Michael

I am trying to manage Firefox browser for our users with MDM. On doing so, I can't able to get expected output on blocking the camera access for certain websites with the following OMA-URI.

./Device/Vendor/MSFT/Policy/Config/Firefox~Policy~firefox~Permissions~Camera/Camera_Block

I can add websites in allow section and even lock the setting so that the users can't change. But facing issues with blocking camera access.

Is there any place where I can see the log if there are any error encountering by any chance? Any insights or suggestions would be greatly appreciated.

Thanks in advance!

I would like access to Firefox Stories but the policy setting for FirefoxHome Stories is false. How do I get to these settings to change the false to true?

Until about a week ago the stories showed up on the New Tab. There is a side section on New Tab for customizing and the section had an option to see the stories. Now that section has no reference to the option.

Any suggestions?

Thanks,

Firefox is used on Windows 11 Enterprise. There is a firefox.cfg in the installation directory (and an autoconfig.js in the ./defaults/pref sub-directory). Everything works fine when a pref(...); entry is written to the firefox.cfg. However, we want the firefox.cfg to call the pref(...); entries from a global_config.js which is saved on the machines public directory.

Therefore, the firefox.cfg says:

// free line lockPref("autoadmin.global_config_url","file:///C:/Users/Public/.../global_config.js");

But firefox does not load whatever prefs are written to the global_config.js. There probably is problems with the formatting of the file path (file:///C:/Users/Public/.../global_config.js). What would the correct formatting look like? Unfortunately, Mozilla´s support guide only includes an example code for a firefox.cfg which calls a global_config.js via http:, but not via file:.

My in house security team, recently suggested that Firefox be marked for automatic updates. I did so reluctantly and within three weeks, my feelings were confirmed. I logged in and hit the firefox button. Not found. OK, where did they move it? Program Files. OK. I opened Firefox. No configuration, no passwords, and no bookmarks.

The help to restore previous bookmarks does not work, presumably because the file was deleted with everything else in Program Files (x86)/Mozilla Firefox.

You should not force an update that will cause the user to lose work -- never, ever.

If you're going to move the installation directory, the user should get a chance to backup first. I did not get that chance and I've lost work. Further, I've lost confidence in your product. I can no longer recommend Firefox to others as I've done for decades.

This is not a good day for you and your product.

Hi,

Looking to upgrade our org to ESR 128.2.0 due to compatibility issues - most notably, embedded PDFs not loading due to Promise.withResolvers() not being implemented on versions prior to 121.

Curious to know if there are any issues or concerns with upgrading manually/pushing this version out - would like to ensure we don't cause further issues in attempting to resolve one.

Dear Mozilla Firefox Team,

I hope this message finds you well.

We manage a network of workstations that frequently utilize the Mozilla Firefox browser. Recently, we have encountered a situation where many of our systems are showing vulnerabilities due to pending browser updates. The updates are being installed successfully; however, users often neglect to restart the browser, which is crucial for completing the update process and ensuring security.

To address this, we would like to inquire if there is an existing Group Policy that can be configured to automatically notify users when they need to restart their Firefox browser to apply the latest updates. Such a feature would greatly assist us in maintaining the security integrity of our workstations and ensuring that users are made aware of the importance of restarting their browsers when prompted.

If this functionality is not currently available, we would appreciate any insights on potential workarounds or future plans to incorporate such a feature.

Thank you for your attention to this matter. We look forward to your response.

Hi,

I am having the issues on more than 1 pc that after updating the firefox esr 128 version to 140 esr version, the firefox does not work properly, specially with xWiki. when i click on xwiki (on-premis server), i can read the contents and all. but when i click edit then it shows the blank page. this is very odd as it happens after updating to 140 version. picture is attached.

Thanks Sheras

Hello!

Currently we deploy Firefox via SCCM Package on our machines. The problem is, that Firefox currently only updates itself when you opened it once. This leads to all sorts of Vulnerability warnings etc.

At the moment these regkey settings in HKLM\SOFTWARE\Policies\Mozilla\Firefox are configured: AppAutoUpdate (REG_DWORD) 0x00000001 (1) DisableAppUpdate (REG_DWORD) 0x00000000 (0)

These two are enough for the updates, when the user opened Firefox (and created a profile).

So we tried the information detailed on this page: https://firefox-source-docs.mozilla.org/toolkit/mozapps/update/docs/BackgroundUpdates.html

To achieve a 100% unattended update we added following Key: BackgroundAppUpdate (REG_DWORD) 0x00000001 (1) which yielded no results. Firefox stayed on his old Version (V131 for this example).

We also added pref("app.update.langpack.enabled", false) in the autoconfig.js File as kind of a 'hail mary' action (bc. the documentation wrote, that this setting should be disabled); but it still does not work.

We've been through this rabbit hole quite some times now, and researching it also yields inconclusive results. (answers like: you still need to start Firefox once, before it can update).

So, what are we missing/doing wrong? Is a true unattended Background Update even possible or is "start Firefox once to create a profile" still the only way to go?

Thanks in advance for your time & help

When I go to some websites, such as Corair.com it hangs. I cannot click on anything. If I try to access specific pages via a search engine the same happens. I can close the browser but the 8+ processes don't terminate so I have to kill them from task manager.

I clear all of my browser history when I close FF so I can't remember all of the sites this happens on, but it was more than just Corsair.com.

I'm using 140.2.0esr, but also had the problem with 140.1.0esr. I did not have this issue on 128.12.0esr (I upgrade to 140 after that).

I tried turning use hardware acceleration off/on, that didn't fix it.

I am just about to try safe mode.

With Firefox 115.14.0esr, 115.2esr and 128.xesr we can`t log in into a company website with a certificate. After the certificate login we end up on the WebSeal again. Http status 302 for pkmslogin.form and pkmscertpromptstagen is called ~12x repeatedly with 302 error each time and then jump back to the login screen.

Hi,

I have 2 machines (Win10 and Win11) with FF 140.3.1esr (32-bit) installed which demonstrates the same failure when I enter one site's url:

PR_CONNECT_RESET_ERROR

Chrome at the same machines goes at this url w/o any failures. Any ideas what to change on "about:config" in FF to allow it opening this url w/o such error?

Co żeście spieprzyli w tej przeglądarce? Claude AI zawiesza całą przeglądarkę. Od kilku wersji coś jest fundamentalnie zchrzanione bo nawet Pikvm nie serwuje obrazu. Do tego popsuliście coś z profilami, że nie można wrócić do starej wersji przeglądarki. Cała masa błędów. Na siłę próbujecie udaremnić działanie wtyczek blokujących szpiegowanie użytkowników?

I am working on deploying Firefox with a GPO and I noticed that a saved password can be easily viewed just by going into the password manager. I found a way to disable the password manager all together, but then you can't save passwords. I am look for a way just to Require device sign in to fill and manage passwords as it says so its not just clicking the eyeball to see the password. I saw this article ( https://support.mozilla.org/en-US/kb/firefox-password-authentification-prompt ) which is how I got the description for this and that seems to be exactly what I want, But I cannot find this setting anywhere in the GPO. Anyone know where it is OR perhaps maybe you could add it?
