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.

Im working on a deployment package for Mozilla Firefox 106.0.1 when launching Firefox on a brand new user it automatically creates a shortuct for private browsing. Im looking for a way to disable this as the package im creating is an appv package and this new shortcut installs in users profile, so it won't be uninstalled. I have searched google but cant find any hits.

We have the following for customization: Application directory\defaults\pref: localsettings.js with these settings: pref("general.config.obscure_value", 0); // only needed if you do not want to obscure the content with ROT-13 pref("general.config.filename", "mozilla.cfg");

Application directory\mozilla.cfg with these settings: // Don't show WhatsNew on first run after every update pref("browser.startup.homepage_override.mstone","ignore");

// Don't show 'know your rights' on first run pref("browser.rights.3.shown", true);

// Disable Policy Notice on First Run pref("toolkit.telemetry.reportingpolicy.firstRun", false);

// Disable checkDefaultBrowser lockPref("browser.shell.checkDefaultBrowser", false);

Application directory\distribution\policies.json with the following settings: {

 "policies": {

Hello,

I am managing Firefox for a very large organization. We have several extension that we deploy using registry keys and we don't allow users to install additional addons. However, since version 102.3 I noticed some extensions that are present on the machine as .xpi files, but should not install unless a specific application is also present, are also being activated. They are enabled in the add-on manager, the information is present in the "extensions.json" and "extension-preferences.json" files. This should not happen. Is there any way to prevent the activation of these files?

Thank you!

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?

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.

Steps:

  • Open Linux server via VNC
  • Open Firefox
  • Search the term "test"

Issue:

  • The google result page doesn't fit into the window and has a horizontal scrollbar to see content on the right hand side

Note: I need my website to fit into browser properly at 100%(default) zoom itself for the purpose of automation because changing zoom level via selenium automation to press ctrl and minus 3 times causes unexpected behavior like even though value is filled in a textbox, it doesn't get sent in the API request payload.

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!

I am deploying Mozilla Firefox using Intune. The application is deployed no problem but there is always the error in Intune portal. I was told that Mozilla Firefox has custom return codes to indicate post-installation behavior. That is why though the application itself is installed and works properly on the device, Intune portal does not know the status of the installation and gives the error. This error causes a lot of issues to the further application management. Dose any one knows what those codes are? Or maybe can point into the correct direction on how to get them. Thank you.
