Komunitné fórum Firefox pre podniky

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.

Using group policy there is various settings required for our users. We have been using the preferences policy located at: Administrative Templates > Mozilla > Firefox > Preferences

This policy requires the use of JSON, we have been using the following which has been working ok:

{ "media.navigator.permission.disabled": { "Value": true, "Status": "user" }, "browser.warnOnQuit": { "Value": true, "Status": "user" }, "keyword.enabled": { "Value": false, "Status": "user" }, "browser.tabs.unloadOnLowMemory": { "Value": false, "Status": "user" }, }

Within the old "Preferences (Deprecated)" there is a setting called "intl.accept_languages" which we are wanting to use but I can't seem to find a way to include this within the JSON. We are wanting to set it to "en-GB".

If I enable this within the old deprecated preferences section it causes the Preferences with the JSON to stop working.

I have tried various combinations of including it within the JSON but neither are working:

"intl.accept_languages": { "Value": en-GB, "Status": "user" }

"intl.accept.languages": { "Value": en-GB, "Status": "user" }

I've checked the Mozilla website here: https://mozilla.github.io/policy-templates/ There doesn't seem to be any reference for the intl.accept_languages setting to be used within the JSON

Please can someone advise?

We are currently considering using Firefox ESR as our default browser but experiencing a few issues and one of them is with our configured SailPoint IdentityIQ Single Sign-On Experience, which uses Basic Authentication.

Issue Description First, the login button needs to be clicked multiple times before access to the site is granted. Once signed in, the Firefox inbuilt authentication dialogue appears, prompting the user to log in again (see the attached screenshot). The landing page is only presented after clicking the login button several times. This creates a poor user experience, sometimes causing pages to load improperly. Interestingly, the same process works seamlessly in Edge Chromium.

Troubleshooting Steps Taken I have already attempted the following: 1. Temporarily disabled all custom and security settings in mozilla.cfg and config.json. 2. Temporarily disabled Firefox Tracking Protection. 3. Allowed third-party cookies for the specific URL. 4. Upgraded Firefox Version to 128.7.0 5. Since our Firefox browser is significantly hardened, I have also enabled and reconfigured the following settings in mozilla.cfg to ensure Basic Authentication is allowed, functions properly, and suppresses Firefox’s authentication prompt, but without success:

network.http.phishy-userpass-length = 255 network.http.use-basic-auth network.automatic-ntlm-auth.allow-non-fqdn network.automatic-ntlm-auth.trusted-uris security.enterprise_roots.enabled security.enterprise_roots.enabled

Observations from SailPoint Team Our colleagues from SailPoint have tested the setup in their environment, and according to them, it works as expected. However, their browser is not hardened, and they have leveraged the SailPoint UI for authentication instead of the built-in Firefox authentication prompt.

Further Investigation • Is there a specific configuration required in the user profile settings? • Network trace analysis shows 404 errors on GET requests and the following error codes on POST requests: • 302 Redirect: Mozilla Documentation • 408 Request Timeout: Mozilla Documentation

Next Steps Is there a specific security setting that needs to be enabled or disabled? Are there any particular Firefox enterprise policies we should modify? I have also attached screenshots for reference. Let me know if you need specific logs or network traces for further troubleshooting.
