Firefox version

   128.2.0esr (64-bit)

Operating system

   Windows 10/Windows11 23H2 Septembre patch

Hello everyone,


maybe you can tell me/explain what the problem could be.

In our company we had Firefox version 115.14.0esr (64-bit) and then we updated to 128.2.0esr (64-bit).

Since version 128.2 ESR we have experienced problems in Firefox when trying to access DNN+ pages (with login). https://www.dnn.de/sport/regional/dresdner-sc-denkt-ueber-uebernahme-der-margon-arena-nach-C3IC74MZ6FE43AKGCZJSKUXA3I.html

In Firefox the content is cut off, in Edge it is displayed normally.

With Edge and Firefox 115.14.0esr the page is displayed normally. No AdBlock installed.

In developer mode I see the errors in the versions, so it shouldn't be that.

Cross-source (cross-origin) request blocked: The same-source rule prohibits reading the external resource on https://gum.criteo.com/sid/json?origi...AAAAAAAA&gdpr=1. (Reason: CORS request failed). Status code: (null).

Cross-source (cross-origin) request blocked: The same-source rule prohibits reading the external resource on https://id5-sync.com/api/config/prebid. (Reason: CORS request failed). Status code: (null).

Any ideas? Thank you very much! :)

I am trying to manage Firefox for company devices via Intune and would like to know if there is a way to uninstall all extensions/add-ons besides one or two approved ones.

I have been able to import the Firefox AMDX into Intune and have made a policy to install uBlock (which works without issue) and I can uninstall specific extensions/add-ins via their Extension ID (also without issue), however I can't see a way to uninstall all extensions. If I try and put a wildcard in the Extension ID field, nothing is affected.

We have a large number of devices with their own user-installed extensions so auditing this and then updating a policy manually with specific extension IDs may be quite painful.

Hello,

I am trying to create a management policy for extensions where all themes are allowed, some extensions are force installed, other specified ones are allowed, and anything else is blocked. I have been scouring the web looking for samples and I just can't get it to work as intended. Here is a sample of what I have written.

{ "*": { "blocked_install_message": "IT has blocked the installation of UNAPPROVED add-ons. Please contact the IT Service Desk to request approval.", "install_sources": "https://addons.mozilla.org/*", "allowed_types": ["theme","extension"] }, "plugin@okta.com": { "installation_mode": "force_installed", "install_url": "https://addons.mozilla.org/firefox/downloads/file/3601147/okta_browser_plugin.xpi" }, "support@lastpass.com": { "installation_mode": "force_installed", "install_url": "https://addons.mozilla.org/firefox/downloads/latest/lastpass-password-manager/latest.xpi" }, "developer@zoom.us": { "installation_mode": "allowed", "install_url": "https://addons.mozilla.org/firefox/downloads/file/4212428/zoom_new_scheduler-2.1.52.xpi" }, "info@katalon.com": { "installation_mode": "allowed", "install_url": "https://addons.mozilla.org/firefox/downloads/file/3826743/katalon_automation_record-5.5.3.xpi" } }

In this current state, I am allowed to install themes, I get the forced installs, but I can install ANY extension. I don't want that.

If I modify the blocking section with [ "installation_mode": "blocked", ], then I only get the force installed plugins and I can't do anything else. It even removes any previously installed themes or plugins not explicitly forced in. The allowed plugins can't be installed either.

I have also tried it without the "extensions" allowed_type but the result did not change. To recap, I need to block any extensions not explicitly pushed or allowed. Would anyone be able to assist and point out what I may be missing please?

~Regards

We are working on implementing Firefox for Enterprise and rolling it out through Intune/Company Portal, one challenge we are encountering is that we have disabled Pocket as thoroughly as we can (followed the guide from Mozilla https://support.mozilla.org/en-US/kb/disable-or-re-enable-pocket-for-firefox) and we are still seeing requests go out to "img-getpocket.cdn.mozilla.net" we do not want Pocket available at all, we do not want queries made to those domains, is it not possible to completely eradicate Pocket?

It wouldn't be a problem but our AV solution (MDE) has a popup every time the URL is queried and blocked.

Hi!

Using Intune, we are setting some settings in Firefox. One that is a bit troublesome is the ExtensionSettings

Currently looks like this:

 },
 "uBlock0@raymondhill.net": {

 },
 "@react-devtools": {

 }

}

I get the Blocked message if I try any of the allowed extentions like uBlock, Dark Reader or React Dev Tools.

I can add that uBlock had "force_installed" (With URL since that is required for force) and that worked fine.

I am using the intune preview feature which allows you to import admx/adml instead of using the custom injection method. Everything works far better then with the injection method, except for one settings:

ExtensionSettings this setting is working when I have only one setting set (ex):

{"someplugin@test.com": { "installation_mode" : "allowed" }}

If I add a second line to the entry:

{"someotherplugin@test.com":{ "installation_mode" : "allowed"}}

I understand this is a new feature, but if I had the correct format that would work for HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox\ExtensionSettings to allow two plugins to work I belive I shouldn't have any issue getting the admx feature to do this, I even tried manually editing the registry setting and it breaks whenever I add the second line to it.

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?

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.

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.

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?

Intune ExtensionSettings Policy No Longer Working in Firefox

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.
