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 pushing out bookmarks company-wide through Intune on users Laptops. I spoke with Microsoft support and the configuration policy is created correctly and I followed Firefox's support page in creating them. It seems that the new JSON script that tells Firefox what bookmarks is unable to parse.

Anyone know if Firefox had an update that prevents intune from sending the JSON file?

Error message given through firefox.

"Unable to parse JSON for ManagedBookmarks"

I work in an enterprise environment. We have certain requirements that we must maintain for our system to maintain accreditation. One of these requirements is to prevent the installation of add-ons using the policies.json file.

We are also trying to develop an extension that adds banners to each page the user interacts with. I understand this can be loaded using the process [https://support.mozilla.org/en-US/kb/deploying-firefox-with-extensions|he...] and does not have to be signed following this [https://support.mozilla.org/en-US/kb/install-system-add-ons-firefox-enter...] .

My question is, before embarking on the journey to create this web extension, can it still be installed following the enterprise process, despite being denied by default by the policies.json? Or is there a way to allow for the extension to be installed by changing the policy?

Been managing bookmarks for users through Intune, but for some reason on my HP Elitebook 840 I keep getting an error "Unable to parse JSON for ManagedBookmarks" I haven't changed anything to the bookmarks before swapping to the HP laptop from a Dell 5410. I have double-checked GitHub for the proper string for bookmarks and everything looks to be correct as well as submitting a support case with Microsoft who checked it and say it is something on Firefox's side that needs fixing.

I am also constantly getting this unknown extension setting. Not sure why I have this or where I can remove it.

We have Firefox-ESR in use and we are using Applocker.

When we enable applocker dll Rule policys and start https://shaka-player-demo.appspot.com page clearkey addon crashes.

We have allowed widevinedrm.dll in applocker rule policys, and we have used Process Monitor to track which dll file / files are being "locked" but we cant seem to pinpoint it.

Where does Firefox-ESR run DRM content and which dll files are needed to run ?

What we know that it is caused by applocker DLL rule policys, when disabling it clearkey addon does not crash and drm content can be played.

Also Applocker eventlogs does not show anything related to this.

Hello. I have trying to test a GPO this week that will lock down the use of extensions. In summary we are shifting to a complete "deny all/allow by exception format".

As a reference I have been using the below article as my source on how to set this up. https://github.com/mozilla/policy-templates#extensionsettings

After reading through the article the base example they have works flawlessly. I have put this base example below.


{

 "*": {
   "blocked_install_message": "Custom error message.",
   "install_sources": ["https://yourwebsite.com/*"],
   "installation_mode": "blocked",
   "allowed_types": ["extension"]
 },
 "uBlock0@raymondhill.net": {
   "installation_mode": "force_installed",
   "install_url": "https://addons.mozilla.org/firefox/downloads/latest/ublock-origin/latest.xpi"
 },
 "https-everywhere@eff.org": {
   "installation_mode": "allowed"
 }

}


The minute I try to change it though the whole thing breaks. For context, I have tried adding 1 password as a forced installed add in, and also try placing it below under allowed. See my example below of the one where I am putting it is allowed. Any idea of what I am doing wrong?


{

 "*": {
   "blocked_install_message": "Custom error message.",
   "install_sources": ["https://yourwebsite.com/*"],
   "installation_mode": "blocked",

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.

Hello,

I have a problem with a pac file in our org. We download it from a server. The basic functionality is applied and it does redirect the desired traffic to the proxy. The problem occurs when the proxy goes down, it then should automaticaly start making direct connections, but the connections fail. We want to proxy only http and https and event that with some exceptions.

It was done according to https://developer.mozilla.org/en-US/docs/Web/HTTP/Proxy_servers_and_tunneling/Proxy_Auto-Configuration_PAC_file#example_6

Is there any problem with PAC file or does the browser have issues with the config?

Thanks for any help.

I'm setting up addon installation through `policy.json`. Below is an example. I am wondering howto configure addons thus installed using the same file. Is it possible? If yes: where to find addon-specific keys/options? As an example: when providing below `policy.json`, starting any fresh firefox profile/installation produces the dialog "Startpage.com - Private Search Engine would like to change your default search engine from Google to Startpage.com - English. Is that OK?", followed by yes/no buttons. I would like to be able to just make the addon do so forgoing the dialog.

Thanks for any pointers.

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?
