Hi, I am in a company where there is 100 and more devices with firefox on it. Right now we are facing a problem where some of it are using version way back into the days such as version 100 115 117 and such. We enabled auto updating but it only updates to version 127 whereas the latest version is 132. We are required to open firefox again for multiple time b4 it gets the latest version. Is there any way to jump those stages and straight updates to the latest version?

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.

Hello,

I installed Firefox 128.2.0esr. I set the next parameters in GPO for settings DNSOverHTTPS: "DNSOverHTTPS": {

                      "Enabled":  true,

"ProviderURL": "https://safe.dot.dns.yandex.net/dns-query", "Locked": true, "Fallback": true }. But when checking via https://www.cloudflare.com/ru-ru/ssl/encrypted-sni/#results I get (screenshot in attachment). As you can see from the screenshot, DNS and SNI did not receive the coveted check marks. Secure DNS We weren’t able to detect whether you were using a DNS resolver over secure transport. Contact your DNS provider or try using 1.1.1.1 for fast & secure DNS. DNSSEC Attackers cannot trick you into visiting a fake website by manipulating DNS responses for domains that are outside their control. TLS 1.3 Nobody snooping on the wire can see the certificate of the website you made a TLS connection to. Secure SNI Anybody listening on the wire can see the exact website you made a TLS connection to.

In my browser / about:config: network.trr.mode = 2 network.trr.uri = https://safe.dot.dns.yandex.net/dns-query

In 128.2.0esr there is no protection against ESNI interceptions and ECH is enabled by default? Or is the problem that the DNS provider does not support the technology from Mozilla? Or what other settings we need use (via GPO)?

Thank you.

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?

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 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.

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.

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.
