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.

Version: Firefox ESR 102.9.0 (64-bit) - Windows 10 Enterprise 22H2

Customers have been complaining for about 6 months that they can no longer drag and drop email attachments from Outlook (Microsoft Office Professional Plus 2019 - Exchange) into a Help Desk formula. I tested dragging from Outlook desktop and from the web version.

Drag and Drop works when using Edge and Chrome.

This is not a major issue, since customers can use the other browsers, but since they would prefer to use Firefox, a fix would really be appreciated.  :-)

We use Firefox ESR for along time in our organisation but with the last update, a specific page wont redirect to the ADFS page. In the latest normal version of Firefox it works and also other browser but not in ESR.

The webpage is https://rx-base.nl/ and https://preprod.rx-base.nl/

We are using the latest version of ESR. It gives a blank page with in the console a error:

Uncaught (in promise) TypeError: Fout bij het oplossen van modulespecificatie ‘@rxbase/root’. Relatieve modulespecificaties moeten beginnen met ‘./’, ‘../’ of ‘/’.

Please advise on what to do.

We are looking to mass deploy Firefox x64 for Windows to all staff in our organization, using SCCM. I know you can set a default home page in mozilla.cfg for all users, including future users who don't yet have a profile on the computer Firefox is installed on. Is there a similar option so I can configure Firefox to always show the menu bar for all users? Preferably, another line I can add to mozilla.cfg so that I can easily copy that to all our machines? 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 trying to manage Firefox Extension using "Extension Setting" via Intune. Source: https://github.com/mozilla/policy-templates/blob/master/README.md#extensionsettings I am testing below JSON for testing. <enabled/> <data id="ExtensionSettings" value=' {

 "*": {
   "blocked_install_message": "Not Allowed contact HelpDesk.",
   "install_sources": ["https://www.example.com/*"],
   "installation_mode": "blocked",

   "installation_mode": "allowed",
   "install_url": "https://prod.extensions.dashlane.com/downloads/firefox/dashlane-latest-fx.xpi"
 }

}'/>

When deployed to test devices, all extension previously installed get removed and Ublock get installed, seem like working as intended but when I try to install any "Allowed" I get the block installed message. I see no error in "about:policies". I don't know where else to look for why its getting blocked?

Any help will be much appreciated.

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

I am installing Firefox via microsoft endpoint, and deploying multi account containers with the OMA-URI policy for extensions. (this blog page is super helpful! https://securitygeneralist.blogspot.com/2019/08/auto-installing-extensions-on-firefox.html )

The extension by default has containers for Personal, Work, Banking, Shopping.

Is there a way to automatically remove that default container list as part of the install?

Even better, is there a way to create a different default containers list through Endpoint?

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.

Hello, in Firefox browser, my organization has always blocked all extensions except for ones we allow through OMA-URI ./Device/Vendor/MSFT/Policy/Config/Firefox~Policy~firefox~Extensions/ExtensionSettings.

About a month ago this stopped working and our end users can now install any extension in the Firefox browser that they choose, without approval, creating a security risk.

When checking in about:policies, there is a policy error: Unable to parse JSON for ExtensionSettings. We have checked with Microsoft Intune support and they verified that the policy looks to be configured and targeted correctly.

Here is a snippet of our JSON, this is a test policy where microsoft support had us remove "about:addons" from the 'install sources'. Both test and production policies are not working.

Is this a bug? Or something wrong with our configuration? Has firefox changed the requirements of the extensionsettings OMA-URI?

Thanks for any help in advance.

Hello,

I am managing Firefox for a very large organization. We have several extension that we deploy using registry keys and we don't allow users to install additional addons. However, since version 102.3 I noticed some extensions that are present on the machine as .xpi files, but should not install unless a specific application is also present, are also being activated. They are enabled in the add-on manager, the information is present in the "extensions.json" and "extension-preferences.json" files. This should not happen. Is there any way to prevent the activation of these files?

Thank you!

Hello,

Firefox 102.6.0esr (x64) Firefox 108.2.0 (x64)

after implementing the bookmarks (JSON) setting by GPO policy, it turns out that an entry for Bookmarks is created in the registry and not ManagedBookmarks, which causes bookmarks not to appear in the bookmarks bar. When I manually rename a registry entry from Bookmarks to ManagedBookmarks, the bookmarks appear properly. Please let me know if I'm doing something wrong or if there really is a problem reported by me.

Yours sincerely Bart

Hello, ever since we moved endpoints from Firefox ESR 91.13 to 102.3, it has become impossible to play any media with Firefox.

No video will play in youtube, for instance (it just loads endlessly as if it would start, but it doesn't).

Can't use radio websites either. Anything with a "play" button (video or sound) does nothing.

This has been tested with a clean profile, a clean install, after allowing autoplay in the settings.

Is there any info on what exactly changed between ESR 91 and 102 that might explain this ? There has been no system change, If I reinstall 91 instead it works again as usual.

No issues anywhere else on the endpoints (Edge, Windows), this is on Windows 10 if it makes any difference.

Tanks for any help on this.
