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:.

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.

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.

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?
