We have put user and computer startup scripts to detect and delete firefox from our enterprise customers. Firefox cannot be kept SAFe through InfoSec.

InfoSec and SAFe require the business be in charge of security which is what our customers understand. They constantly find firefox out of date and vulnerable. We have tried over and over to use the firefox admx files to force background update both at the computer and user OUs but find that users can uncheck the box and it remains vulnerable and out of compliance. Edge and Chrome can be controlled by the business (not end user) through group policy and kept up to date and we never find either out of date by implementing our policies.

Firefox constantly tells end users how to check the boxes and no group policy can enforce them as we don't see the registry updated even though we even put a registry patch in, firefox is still in the control of the end user and not SAFe. If you don't know what I mean by SAFe, check this out.

Hi,

I've been struggling for a week to try and get our extensions managed in Firefox. Firstly I tried doing it in Intune through the Extension Management setting in the ADMX however that wouldn't work as it couldn't parse the JSON. Then I've tried using the OMA-URI ./Device/Vendor/MSFT/Policy/Config/Firefox~Policy~firefox~Extensions/ExtensionSettings

I'm now getting a straight up error in Intune -2016281112 (0x87d1fde8). I've followed the documentation as best as I can but it still doesn't seem to work. In the Intune logs there is no record of the Config profile even being attempted. Any ideas as to what is causing this error? Here is the full code being used for the OMA-URI string:

Hi all,

we are using Mozilla Firefox ESR in our enterprise environment.

Is there a documentation which URL's Firefox uses when (Mozilla Maintenance Service) when it tries to update his version ?

We have tried with following URL's on our Firewall:

aus.mozilla.org aus2.mozilla.org aus3.mozilla.org aus4.mozilla.org aus5.mozilla.org download.cdn.mozilla.net archive.mozilla.org ftp.mozilla.org

It is finding the new version, but when trying to download the update it fails.

Thank you for any help on this case.

We have 50 workstations set up for certain jobs and the users roam as needed. Each workstation has two printers using different media. the printers are controlled by having two instances of Firefox with each having a user profile to use one printer or the other. In addition to printer settings we set a number of other profile settings such as silent printing etc.

Having a profile per user requires a great deal of setup work to allow different users to log in with authentication and to align the printers with the programs which will print to them.

A solution that would allow us to write a copy of a master profile to each new user via a program would be nearly perfect. Thank you,

Hi Team, I'm using the Zscaler in my network, when I use the Firefox, appear the error:

"Software is Preventing Firefox From Safely Connecting to This Site

www.googleadservices.com is most likely a safe site, but a secure connection could not be established. This issue is caused by Zscaler Root CA, which is either software on your computer or your network.

What can you do about it?

www.googleadservices.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely...." Picture 1

I have root certificate in path: /usr/share/ca-certificates/mozilla$ Picture 2

I run the command for updates CA but it doesn't work: sudo update-ca-certificates

Errors keep popping up.

The certificate not appear in the Certificate manager > Authorities Picture 3

But if I open the firefox > Settings > Privacy & Security> Certifcates > View Certificates > Import And I import the certificate ZscalerRoot.crt and I mark the option "trust this CA to identify websites" the firefox works, and I can open the site without error message.

Picture 4

And the certificate appear in the manager certificate: Picture 5


How can I put the command terminal certificate, which I have on hundreds of machines?

Note: I need to put the certificate only for internet access.

I posted this previously and got zero response and the post is now archived. Hoping for better luck this time.

We have rolled Firefox ESR to all of our computers. On some of them the Maintenance Service is working correctly and installing updates with no user interaction. On other computers, users are getting a UAC prompt to enter admin credentials to install updates. I have tried various changes that I have found across the web from Deleting the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MozillaMaintenance\Security to uninstalling and re-installing the Maintenance Service. All of the users/computers have the same policies applied via Group Policy (Application Autoupdate: Enabled and Disable Update: Disabled) and are not local admins.

Hi,

I deployed the last Firefox ESR update and I just found about this new feature : https://support.mozilla.org/en-US/kb/manage-downloads-preferences-using-downloads-menu

So files are now downloaded and users are no longer prompted for what to do. My question is can we change this to "Ask whether to open or save files" using policies.json?

Kind regards,

Hi, Background: a few months ago I had to redeploy the CA for a network I manage. I was able to do so and publish the new intermediate CA's cert via Active Directory. Since then, I've updated certs on webhosts with certs from the new CA. Whenever a user uses FF (version 91.12.0) to browse to a site with the newly signed cert, I get an error stating "sec_error_ocsp_old". I've been able to temporarily advise users to disable OCSP Validation in FF security settings, but I'd REALLY like to fix this.

Other browsers (Edge, Chrome, Opera) all load the sites without issue.

Using this the below article, I double checked the time settings on the CA, Webserver, and clients: https://support.mozilla.org/en-US/kb/troubleshoot-time-errors-secure-websites

All the machines/VMs in question show the same time source, time, time zone, and sync interval.

I'm at a loss for what is happening. Any help would be greatly appreciated.

Hi,

I've been tasked to make some changes to the way users deal with logins and passwords in the office. So, in short, one of the issues is this: is there ANY way to disable (I'd say "hide" is more accurate) the about:logins page on Firefox?

  • pref.privacy.disable_button.view_passwords (with a lock pref) in autoconfig only disables the "View saved logins" button in Settings.

As for policies:

  • a few policies for blocking about: pages do exist - BlockAboutAddons/Config/Profiles/Support, but can't find one, say, "BlockAboutLogins" or something like that.
  • PasswordManagerEnabled set to false disables the password manager completely, including about:logins, password autofill is disabled as well - not what I need.
  • WebsiteFilter, as expected, doesn't treat about: as a protocol, so it can't be done there either.


Any help is appreciated. Thanks in advance!
