Hi All, I want to block traffic on firefox externally for managed devices via Intune, following the import of the ADMX/ADML files into intune.

Having read https://support.mozilla.org/en-US/kb/managing-firefox-intune I have set '\Mozilla\Firefox\Exceptions to blocked websites' to the following; //*.mydomain.com/*

Which works, however, I also want to add hosts that are only resolving on IPs and not DNS. I can add specific IPs if known, but is there a way I can allow IP ranges? Ie

//10.10.*/* (this doesn't currently work) Of the included screenshot, only the wildcard for mydomain.com and the specific IP currently work

I've looked over the link that is recommened in the policy (indirectly) and can't see an option for allowing an IP range. https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/Match_patterns

If there is a better way to do this via intune for firefox only, please let me know.

Thanks

I am having the same issue as this other user here: https://www.reddit.com/r/sysadmin/comments/17wvuwh/help_pinning_extension_in_firefox_with_gpo/

Preliminaries -- Initially (before trying to force-pin), I had these GPOs enabled:

Extensions to Install -> https://addons.mozilla.org/firefox/downloads/file/4410896/bitwarden_password_manager-2024.12.4.xpi

Prevent extensions from being disabled or removed ->

• {446900e4-71c2-419f-a6a7-df9c091e268b}
• {3f6129fb-6c55-4452-ab6f-7c109b2301df}
• https://addons.mozilla.org/firefox/downloads/file/4410896/bitwarden_password_manager-2024.12.4.xpi

(Those GPOs above all work.)

What I'm trying to do: Force-pin Bitwarden.

I believe I've followed the documentation correctly (except for not including a "*" case): https://mozilla.github.io/policy-templates/#extensionsettings

I've enabled this GPO with this value:

Extension Management ->

{

 "{446900e4-71c2-419f-a6a7-df9c091e268b}": {
   "default_area": "navbar"
 }

}

After running various "GPUpdate"s and whatnot, the option to uncheck "Pin to toolbar" is still available to click.

I've verified in "about:policies#active" that the JSON item appears next to "ExtensionSettings" and that there are no errors listed in the "Errors" tab.

I've also verified that it appears in the correct location in the Registry.

Since another user had the same issue (Reddit link above), I figured it'd be a good idea to check in with y'all to see if we are missing something.

Thanks for your help!

After updating to v132 I have noticed a significant increase in the load times for some websites that our users connect to. Using v131.0.3 I usually see < 1 second load times for the two websites I am monitoring but after upgrading to v132 it is consistently taking 18-19 seconds for the same page. I have tried uninstalling v132 and reverting to v131 and it immediately goes back to the much faster load times. I have also tried installing various v133 releases and I see the same performance issue as for v132.

The environment I am working in is behind a network firewall with relatively restrictive internet access and I am wondering whether there are sites that Firefox is trying to connect to for the new anti-tracking or suspicious activity features (or anything else) that are being blocked and are therefore causing timeouts and retries that are bumping the total load time up.

Can anyone think of anything else I could check or change?

Debian 12 Linux on Dell laptop. Current "updated version" Firefox ESR 128.4.0esr (64bit) I received an update notice for Firefox ESR this morning. After running the Update, I lost the status bar. How can I get it back?

I'm setting up a cloud-init to make it easier to deploy Linux workstations. I want to display the various links to my sites on my Firefox browser. Bookmark my services. Do you think this is possible? I've already applied a rule to retrieve certificates, but it seems complicated for bookmarks.

Here's an extract  :

{

 "policies": {
   "Bookmarks": [
     {
       "Title": "Main",
       "URL": "https://service.net",
       "Folder": "Bookmarks Toolbar"
     },
     {
       "Title": "Service 1",
       "URL": "https://service1.net",
       "Folder": "Bookmarks Toolbar"
     },
     {
       "Title": "Service 2",
       "URL": "https://service2.net",
       "Folder": "Bookmarks Toolbar"
     },
     {
       "Title": "Documentation",
       "URL": "https://docs.net",
       "Folder": "Bookmarks Toolbar"
     }
   ]
 }

}

Le 05 novembre 2024 Bonjour, Je ne parviens pas à faire la mise à jour FireFox. J'utilise un MAC OS X version 10.9.5 Processeur 2,7GHz Intel Core 15 Mémoire 8 Go 1600 MH DDR3 MERCI de bien vouloir me répondre en Français. Bonne journée. Cordialement.

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.

Is there any parameter or group policy similar to Chrome "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome\AutoSelectCertificateForUrls]", as we implemented application with Certificate sign-in, it pop-up every time when navigating to different on-prem servers, we enabled Group policy for MSEdge & Chrome, but need to do same for Mozilla Firefox.

I need expert advice on this subject matter.

the settings ExtessionSettings does not show up to be able to modify even tho it is on the ADMX file (5.11)? Should I use the older Extensions policies? I want to install and pin an extension from the store.

Hi everyone. I have installed Firefox on all windows 10 workstations and I have also installed latest Firefox Group Policy ADMX on Server. I need to set some preferences on all Workstations. The preferences that I want to set are the ones that can be found in about:config.

But the problem is that only some of these preferences exist in Group Policy by default and it says "deprecated". I know that I can add additional about:config preferences in a Group Policy object called "Preferences". But no matter how I enter the format or how I change the JASON file, no preference policy is applied to Firefox in workstations. By the way when I change "Preferences" gpo in group Policy the next Policy called "Preferences (JASON on one file)" does also change. I have thoroughly searched the web and Mozilla support and have tested all suggestions but all to no avail. Can you please help me and Give me an example of how to do that? I would appreciate any answer in advance.

Hello,

Toggle button yahoo setting - desktop notifications, not working

I am facing this problem only in firefox windows 11. Sometimes it works but rarely and inconsistently. I have tried the suggested solutions..

At your disposal

Hi All, I have been on the struggle bus lately trying to get the application handlers set properly in our GPO. I am trying to get PDF, webp, avif to open in browser, and jnlp to auto launch Java. Any help will be greatly appreciated!

{"application/pdf":{"action":3,"extensions":["pdf"]},"image/webp":{"action":3,"extensions":["webp"]},"image/avif":{"action":3,"extensions":["avif"]},"application/x-java-jnlp-file":{"action":4,"handlers":[{"name":"javaws.exe","path":"C:\\Program Files (x86)\\Java\\jre-1.8\\bin\\javaws.exe"}],"extensions":["jnlp"]}}

I need to be able to hide the Extensions button from the toolbar. Is there a way to do that outside of the user.js or prefs.js? Preferably I'd like to do this though the policies.json file though I could not find any options for this.

I'm a security analyst. I would like to get email notifications on security advisories, alerts and vulnerability information regarding Firefox to stay up to date. Please help on how I can get the subscription?

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

Good afternoon,

We're currently trying to set up a Hardening Guide for Firefox ESR but are struggling with a few policies and setting wildcards.

For example, we're trying to set an origin in Cookies > Block Settings to something like "*", and we get the error "Ignoring parameter "*" - not a valid origin."

In Chrome / Edge you can set a wildcard like this: [*.]google.com for example - we receive the same error message for this.

Can you do such a thing for Firefox ESR without having to list every site you want to block?

ESR Version: 115.6.0esr (64-bit)

Kind Regards, Ethan Jerrum
