Hi,

I've been tasked to make some changes to the way users deal with logins and passwords in the office. So, in short, one of the issues is this: is there ANY way to disable (I'd say "hide" is more accurate) the about:logins page on Firefox?

  • pref.privacy.disable_button.view_passwords (with a lock pref) in autoconfig only disables the "View saved logins" button in Settings.

As for policies:

  • a few policies for blocking about: pages do exist - BlockAboutAddons/Config/Profiles/Support, but can't find one, say, "BlockAboutLogins" or something like that.
  • PasswordManagerEnabled set to false disables the password manager completely, including about:logins, password autofill is disabled as well - not what I need.
  • WebsiteFilter, as expected, doesn't treat about: as a protocol, so it can't be done there either.


Any help is appreciated. Thanks in advance!

During a client Audit earlier this week we were dinged on not having the option in Firefox ESR to block manually saving Addresses and Credit Cards. We have the autofill disabled however users can still manually add credit cards and addresses and this poses an issue with our call center agents handling Credit Card info. I'd like to be able to gray out the Saved Addresses and Saved Credit Card boxes so as to prevent agents from manually entering card data into it using a GPO or Registry setting that we can push and apply to all our domain PCs. Ideally, if we could add an entry to the JSON preferences in the Mozilla GPO that would gray those options out that'd be best but any option that removes the users ability to add CC info would be acceptable.

We downloaded the GPO Templates for AD and looking to customize Firefox.

We would like to disable Forms and Autofill: Autofill addresses Autofill credit cards

Also would like to lock down so they can't reenable if possible.

We would like to do this all through GPOs if possible. I found these in the about:config: extensions.formautofill.addresses.enabled extensions.formautofill.creditCards.enabled

But again want to do through the GPO. Is this possible?

Side note while working on GPOs, I set Exceptions for the popup blocker and they are not showing up in the browser. I also filled out to remove Search Engines but they all still appear in the browsers. These two GPO settings don't appear to be working.

Hi there,

We are currently utilizing Windows Server 2019 as our development server. To maintain security protocols, we have implemented a Group Policy to block internet access on this server. Initially, this configuration successfully restricted internet access on all browsers, including Firefox. However, recently we encountered an issue where internet access became available solely through the Firefox browser, posing a significant data security risk.

Upon investigation, we discovered that Firefox allows users to modify proxy settings, effectively bypassing our Group Policy restrictions. Unlike other browsers, Firefox permits users to adjust proxy settings without sufficient rights, thus overriding our established restrictions.

To mitigate this issue, we require guidance on enforcing Group Policy settings within Firefox to prevent unauthorized alterations to proxy settings and ensure internet access remains restricted. It's important to note that Firefox is exclusively utilized for development purposes on our server.

Your assistance in resolving this matter would be greatly appreciated.

Regards, Hiten

I am looking for information regarding the support life for settings that are defined in the Preferences (Deprecated) section of the ADMX templates provided in GitHub. There doesn't appear to be a definitive answer as to when these preferences are no longer applicable to a version of Firefox. The term "Deprecated" certainly applies they're on their way to extinction. But only a small handful of preferences have been ported over to non-deprecated template settings (like Auto Update). Is there an expected version of Firefox where all these preferences are meaningless? Or will they be supported indefinitely? "Industry recommendations' from 3rd party security vendors are bloating my policies in the domain space and I can't definitively say they are 'no longer supported as of version xyz' for all these Firefox Preference settings, which happen to be about 80% of the security parameters defined by STIG and/or CIS Workbench.

Either an AMDX template with this option or a Registry will do the trick

I have a need to use regular browser (not kiosk), but disable the "open downloads folder" once a file has been downloaded. This is opening a file manager (thunar or alike) which then allows the user to browse the filesystem and open a terminal emulator from /usr/bin.

Using the policies, I am able to prompt for downloads, or select a download location, however I have been unable to completely stop the user from opening the download folder which opens a file browser.

Is there any way I can select policies or profile options for disabling the option for opening download folder?

Hi Team, I'm using the Zscaler in my network, when I use the Firefox, appear the error:

"Software is Preventing Firefox From Safely Connecting to This Site

www.googleadservices.com is most likely a safe site, but a secure connection could not be established. This issue is caused by Zscaler Root CA, which is either software on your computer or your network.

What can you do about it?

www.googleadservices.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely...." Picture 1

I have root certificate in path: /usr/share/ca-certificates/mozilla$ Picture 2

I run the command for updates CA but it doesn't work: sudo update-ca-certificates

Errors keep popping up.

The certificate not appear in the Certificate manager > Authorities Picture 3

But if I open the firefox > Settings > Privacy & Security> Certifcates > View Certificates > Import And I import the certificate ZscalerRoot.crt and I mark the option "trust this CA to identify websites" the firefox works, and I can open the site without error message.

Picture 4

And the certificate appear in the manager certificate: Picture 5


How can I put the command terminal certificate, which I have on hundreds of machines?

Note: I need to put the certificate only for internet access.

So I followed the guide https://github.com/mozilla/policy-templates/blob/master/README.md#extensionsettings and tried to set up the config. We are using the latest ESR build but after the settings is applied I still dont have working extensions.

Here is the code

}

I have placed the settings in HKCU but also tried in HKLM and there has been no difference. in each case I get Unable to parse JSON for Extensionsettings when checking the about:policies section and when I look at the registry I see the REG_MULTI_SZ value but when i click on it to read it I get another error message. Cannot edit ExtensionSettings: Error reading the values contents.

I tried re-entering the code and tried not listing the install URLs and even tried only listing 1 item. I haven't been able to get past this error so any help would be greatly appreciated.

Issue with Blocking Websites in Mozilla Firefox via Group Policy

We followed the links below to block internet access in Firefox browser:

https://www.youtube.com/watch?v=fAGYYX5hYb8 https://github.com/mozilla/policy-templates/releases

We downloaded the ADMX and ADML files. Using these files, we were able to locate Mozilla Firefox in Group Policy Management and successfully block all websites in the Firefox browser using the pattern :///*.

However, we encountered an issue with exceptions. We do not wish to block certain websites, including localhost. We attempted to use the "Exceptions to block websites" option, providing values such as ://msn.com/ to exclude specific sites. Unfortunately, this approach did not work as intended. For instance, msn.com is one of the websites we want to allow, among others and also localhost.

We require assistance with the following issue: "Exceptions to block websites" is not functioning properly within the group policy of Mozilla Firefox.

When setting Windows to "Require DoH", firefox will not resolve DNS addresses, regardless of which "Enable secure DNS" setting is picked in FireFox security settings tab.

I expected at least "Off -- Use your default DNS resolver" to work.

If Windows is configured to just "Allow DoH", Firefox has no issues resolving DNS addresses, for any of the Firefox policy settings.

For reference, you can find the DoH policy setting in windows group policy editor, here:

gpedit.msc

Computer Configuration -> Administrative Templates -> Network -> DNS Client -> Configure DNS over HTTPS

(Have to enable it, then select Configure DoH options: Require DoH.)

you may need to issue a gpupdate /force for the setting to be picked up quickly.

We have a customer using our SaaS solution running through Firefox 91.12.0 ESR. The web application we provide requires access to the camera on the local machine so we can capture a photo. We give them instructions and they configure their instance of Firefox to ALLOW access to the camera, along with several other adjustments (like allowing pop-ups, and no autofill).

However, whenever they restart Firefox the camera permission reverts back to the DEFAULT of Always Ask. The other settings adjustments we make, like pop-ups and no autofill stick around, but not the camera setting.

We've checked the PREF.js file in the Profile folder and that doesn't appear to be a problem. On our in-house machines we are running the same version of Windows and Firefox and cannot reproduce the problem.

The customer has recently applied the upgrade from an earlier version of Firefox ESR to 91.12.0. The customer has also imaged the PC and copied over to a large number of additional machines for use around their organization. This problem is causing a serious disruption to their deployment of the updated PC's as we work with them to try and troubleshoot the problem.

Any ideas on what to try would be appreciated.
