Firefox (129.0.2) displays "401 - Unauthorized: Access is denied due to invalid credentials" (see attached image)

I have tried various combinations of setting and not setting the following in Firefox:

  • network.negotiate-auth.trusted-uris
  • network.negotiate-auth.delegation-uris
  • network.auth.use-sspi

For the URI settings I have tried both .domainname.domainextension and https://servicename.domainname.domainextension

In Windows 10 Control Panel -> Internet Options, the site is in "Trusted sites" using a domain wildcard, and also "Local intranet" and both "Automatic logon" and "Enable Integrated Windows Authentication" are enabled. I suspect those setting aren't relevant since other browsers are authenticating without error or prompt, but calling this out to show that I've covered that base.

The web service is served by IIS 10.0 on Windows Server 2022 and the authentication provider list only includes Negotiate, but I don't believe this issue has anything to do with IIS or its configuration as, again, other browsers are authenticating without error or prompt.

Anything else to check?

Thank you for any guidance you can offer.

Hello,

I am reaching out to gain information on ADMX GPO policies. We are retiring Policy Pak which used to add all the policies and secure Firefox for Enterprise. What we noticed is that Policy Pak used the app set to apply these policies and we are noticing that native GPO's for the most part to match the Policy Pak policies is not as accurate for GPO's My ask here is there any Most Viable Product suggestions to apply Native GPO's for securing Firefox.

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?

Hi All,

I'm using Firefox on 24 PC's in a primary school computer Lab, I have had reports of students installing extensions and plugins that i wish to stop, also i've had issues with students not signing out of their email and other students gaining access.

Im looking for solutions for the following and was hoping someone could point me in the right direction -

1. Disabling the installations of extensions and plugins. 2. Clearing browsing history/logging out of any accounts. 3. Locking settings so students can't change settings.

Any help would be greatly appreciated. Adam

I'm a newbie using Debian and Deb 12 ships with Firefox ESR and I've decided to stick with it instead of the regular release, 'cause it breaks some extensions I have. However, I want to upgrade to the latest ESR version, how do I do it? I tried going to (https://www.mozilla.org/en-US/firefox/all/#product-desktop-esr), but the file for linux 64 bit is a .tar.bz2 file, which I have no idea how to compile.

Firefox ESR/Duo: Not reporting minor version in user agent

We use ESR due to its stability and long term security updates, and we use Duo as our SSO/IDP.

We have Duo set to deny login when the browser is more than 6 mo out of date, but due to the way FF reports only the main version number via the user agent Duo is unable to determine that FF ESR is actually up to date and thinks that it's too old and my users are being denied login or getting an erroneous message about needing to update their browser.

Is there a way to set FF to report it's whole version to Duo? We would prefer not to have to "outlaw" FF in our prod environment if at all possible.

I am trying to manage Firefox for company devices via Intune and would like to know if there is a way to uninstall all extensions/add-ons besides one or two approved ones.

I have been able to import the Firefox AMDX into Intune and have made a policy to install uBlock (which works without issue) and I can uninstall specific extensions/add-ins via their Extension ID (also without issue), however I can't see a way to uninstall all extensions. If I try and put a wildcard in the Extension ID field, nothing is affected.

We have a large number of devices with their own user-installed extensions so auditing this and then updating a policy manually with specific extension IDs may be quite painful.

My company has been using the same customized autoconfig.js without issue since last year's FF 115 esr release on our Ubuntu servers.

cat /opt/firefox-115.13.0esr/defaults/pref/autoconfig.js pref("browser.tabs.inTitlebar", 0); pref("general.config.filename", "firefox.cfg"); pref("general.config.obscure_value", 0); pref("general.config.sandbox_enabled", false); pref("pdfjs.annotationEditorMode", 1);

Now we are testing the 128 esr next releases with the same config and getting the failed to read the configuration file. please contact your system administrator error

cat /opt/firefox-128.1.0esr/defaults/pref/autoconfig.js pref("browser.tabs.inTitlebar", 0); pref("general.config.filename", "firefox.cfg"); pref("general.config.obscure_value", 0); pref("general.config.sandbox_enabled", false); pref("pdfjs.annotationEditorMode", 1);

If remove pref("general.config.obscure_value", 0); or set it to 1, the error goes away, but our actual firefox.cfg does not get read and are configs are not present at all.

Switching to Firefox ESR with Microsoft Intune - Need Help with Password and Bookmark Sync Without Mozilla Accounts

Hello Mozilla Community,

I am an administrator in a company where we currently use Microsoft Intune for software distribution. We are currently deploying Firefox 76.0, which automatically updates itself and is no longer at version 76.0. However, we are planning to switch to the Firefox ESR version.

In our organization, we are not allowed to use Mozilla accounts for syncing passwords and bookmarks due to internal policies. Our goal is to make this transition as seamless as possible for our users, with as much automation as possible, while still ensuring that they can sync their passwords and bookmarks effectively without relying on Mozilla accounts.

Is there a way to achieve this, perhaps through a third-party tool or another method that integrates well with Intune and respects our privacy requirements?

Any guidance or suggestions to make this process smooth and user-friendly would be greatly appreciated!

Thank you in advance for your help.
