Firefox for Enterprise Support Forum

I am an admin of some servers, i modify the proxy settings of firefox in a GPO, and it works, but now ont thing is that users can modify the settings of "No proxy for" in Connection Settings, then add the urls, then users can access to any web site which they want to, is there a method to disable this? thanks.

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.

We try to deploy Extension Management Settings via GPO.

Goal is to allow only whitelisted extensions, but don't block themes, dictionaries and locales.

Below find the JSON-settings deployed to the client, which should allow all themes and whitelisted extensions. Unfortunately this blocks everything except whitelisted IDs. See example screenshot with error-message, when trying to install a theme. We don't want to whitelist locales or themes, they should be still allowed for installation.

What I'm doing wrong? - Thanks for your feedback.

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 There doesn't appear to be a definitive answer as to when these preferences are no longer applicable to a version of Firefox.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.

in our organisation i need several domainnames to be added in network.negotiate-auth.delegation-uris and network.negotiate-auth.trusted-uris, so that sso for some webapplications is working. some are allready in the list. when i make changes to the list, everything is working ok, but when i clos all mozilla windows and restart mozilla, the changes are gone.

Hello

I am looking for a way to disable the QUIC protocol in Firefox by GPO. I got your latest AMDX templates but I don't see the option to modify network.http.http3.enabled.

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

Thanks

Environment: Windows 10 22h2 clients, latest ESR build, Domain servers Windows 2016 or better.

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.

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?
