Firefox Enterprise コミュニティフォーラム

I am using Ubuntu Linux on a desktop PC running Firefox in kiosk mode going to a specific web page - Every time Firefox does an update (since version 147) the kiosk mode stops working. The very latest update, after a reboot, just shows the menu bars and not Firefox going to that specified web page. Has the kiosk code changed since v147 ?

There is a enterprise download for windows and Apple but i do not see a download option for Linux from this site. https://www.firefox.com/en-CA/browsers/enterprise/

But there is a download for the ESR version from https://ftp.mozilla.org/pub/firefox/releases/

Is there a reason why Linux is not on the main enterprise download page ?

How to disable Firefox add-ons in order to block to install temporary extensions. I am generating policies via Firefox Policy generator. {

 "name": "myconfig",
 "time": "2025-12-14T13:17:27.479Z",
 "configuration": {
   "arrayfields": {},
   "checkboxes": {
     "BlockAboutAddons": true,
     "BlockAboutConfig": true,
     "BlockAboutProfiles": true
   },
   "input": {},
   "textareas": {},
   "select": {}
 }

}

GNU nano 8.6 /etc/firefox/policies.json {

 "policies": {
   "DisableFirefoxStudies": true,
   "DisableTelemetry": true,
   "DisableSystemAddonUpdate": true

   "Preferences": {
     "app.normandy.enabled": false,
     "app.shield.optoutstudies.enabled": false,
     "extensions.autoDisableScopes": 15
    }
  }
} Hidden modifications to settings and extensions is absolutely not OK!!!!!!

This is a security environment.

Hi all,

For quite a while I'm working together with others on a voluntary base (nobody gets money) as members of a computer-club, a charitable NGO and NPO (in German: gemeinnütziger Verein) for seniors in order to bring them closer to the use of digital devices and media. It's not only teaching, but administrating the hard- and software as well.

I can remember that it was possible in former versions of Firefox to include at least a script into "defaults->prefs". I think it was user.js (not sure) in the installation folder to define common preferences to be fixed, like proxi settings. It always worked well, preventing non-privileged users from making any unwanted changes. As a I found out there must have been a very similar way to include add-ons (like uBlock Origin).

Unfortunately all content I found was older than about 10 years. When trying setting up Firefox as it is now, my test system didn't care about anything I've tried.

I'm talking about > 50 Windows-PC having in average 3 user profiles each (for teaching more than 400 members). We are amateurs regarding PC administration, except some network ex-professionals. "Baking" installation media including our needs, as I already found on Mozilla's pages, seems to be beyond our abilities as well as distributing a fitting profile (we don't have a MS-server), not speaking about Group Policies.

Is there any usable guideline for people like us? Today, each FF-installation looks different and I would like to unify this as easy as possible.

I have a few questions regarding the auto-update policy of extensions installed via ExtensionSettings with the force_installed installation mode.

1. Can the extension receive auto-updates just like extensions installed through normal means? (e.g. extensions installed from https://addons.mozilla.org)
2. If so, will the user be notified when the extension requests new permissions?

I am trying to reach an internal company website ([URL]), with a certificate chain rooted in a company certificate authority. This works fine in Chrome, and worked in Firefox on my previous computer. But i recently got a new machine, and something somewhere is not quite right. I get an error message looking like this (between the ~~~s):

~~~ Someone could be trying to impersonate the site and you should not continue.

Web sites prove their identity via certificates. Firefox does not trust [URL] because its certificate issuer is unknown, the certificate is self-signed, or the server is not sending the correct intermediate certificates.

Error code: SEC_ERROR_UNKNOWN_ISSUER

View Certificate ~~~

If i click on the error code, i get these details:

~~~ [URL]

Peer's Certificate issuer is not recognised.

HTTP Strict Transport Security: false HTTP Public Key Pinning: false

Certificate chain:

[certificate]

[certificate]

[certificate]

~~~

If i click 'View Certificate', i get a chain of three certificates:

1. Subject common name = [certificate]
2. Subject common name = [certificate]
3. Subject common name = [certificate]

If i go to Settings > Privacy & Security > View Certificates > Authorities, i can find both the [certificate] certificates. As far as i can tell, they are identical - i can open the certificate from 'View Certificate' and the corresponding one from the certificate manager and flip between tabs, and all the details are the same.

I am using Firefox 120.0, via a flatpak, on Ubuntu 22. I have given the flatpak access to /etc/ssl/certs, where my company's internal CA certificates are located.

To me, this seems like it should all work. The server has a certificate signed by an internal CA, which is signed by another internal CA, and both those internal CA certificates are in my certificate manager. So what is going wrong? Is there any way i can debug this?

Hi, I keep getting a message that I should update to a newer version of Firefox on Ubuntu. The problem is: I click on the install for 64 bit button, A ...tar.xz file downloads to my desktop, and the process ends completely. How to proceed?

Thanks, Ildikó
