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.

Currently we are setting our GPO to set users homepage to our intranet. The issue is in Firefox i can't see how to disable Open previous windows and tabs in the Genral Settings .

FF 102.3.0esr (64-bit) says 'You are currently on the update channel' but doesn't update. I see 102.5.0 is available. Originally said policies managed by organization. Enterprises Policies. I Deleted [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox]. Enterprises Policies now gone, but message hasn't changed nor can I update.

So we update Firefox via PatchMyPC from SCCM. We don't want to disable Firefox Updates. The issue is how do you stop the Update notification popup every time you start Firefox. You don't have this issue on Edge and Chrome

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 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.

Every time you open Firefox, you will prompt old version bookmarks, history, and passwords, and you can't use them. Choose to opt out or create a new personal file. There are also prompts for the upgrade, and the downgrading version is unsuccessful pls help me

Bonjour, Je travaille dans un musée. Nous utilisons Firefox sur des pc accessibles pour le public. Comment accéder à "aboutNetErrorCodes.js" pour l'éditer. Je souhaite remplacer le message par défaut de Firefox et rediriger vers une une page en local. Merci pour votre aide. Yves

Hi,

i'm running Firefox on +70 Windows 10 PCs in three labs in a university. I've applied a computer configuration GPO with AppAutoUpdate enabled, BackgroundAppUpdate enabled and DisableAppUpdate disabled to my PCs, but it looks like i don't get automatic updates. In my labs i see some workstations have Firefox 108.0.1, but most workstations still have Firefox 107.0.1...

As my users can switch between workstations and labs, this leads to the annoying 'older version' message box when a user worked on a PC which already got the update and later uses another PC which didn't get the update. The users are also forced to create a 'new' profile then, which is quite problematic because of the size of the roaming profiles.

Any hints?

Hello, ever since we moved endpoints from Firefox ESR 91.13 to 102.3, it has become impossible to play any media with Firefox.

No video will play in youtube, for instance (it just loads endlessly as if it would start, but it doesn't).

Can't use radio websites either. Anything with a "play" button (video or sound) does nothing.

This has been tested with a clean profile, a clean install, after allowing autoplay in the settings.

Is there any info on what exactly changed between ESR 91 and 102 that might explain this ? There has been no system change, If I reinstall 91 instead it works again as usual.

No issues anywhere else on the endpoints (Edge, Windows), this is on Windows 10 if it makes any difference.

Tanks for any help on this.

Hello,

Firefox 102.6.0esr (x64) Firefox 108.2.0 (x64)

after implementing the bookmarks (JSON) setting by GPO policy, it turns out that an entry for Bookmarks is created in the registry and not ManagedBookmarks, which causes bookmarks not to appear in the bookmarks bar. When I manually rename a registry entry from Bookmarks to ManagedBookmarks, the bookmarks appear properly. Please let me know if I'm doing something wrong or if there really is a problem reported by me.

Yours sincerely Bart

We have configured Windows Single Sign On to Microsoft 365 in Firefox 102.6.0esr (64-Bit).

We have embedded a Video from the new Microsoft Stream on SharePoint Online into a SharePoint 2019 onpremise Site via the provided iFrame. Here every user gets an endless Login Loop (see Screenshot).

If you open the deeplink to the video, Single Sign On works perfectly.

And this also works in Microsoft Edge, why the Microsoft support is not willing to analyse this issue further.

Do you have any ideas how to narrow down the problem?

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:

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.

I am currently trying to configure a very old network switch that requires Java. I have tried using the Firefox ESR (Extended Support Release) but i cannot seem to find or get the java plugin installed. I also tried downloading and installing firefox version 51.

What could i do to resolve this issue? I also tried using internet explorer but my computer refuses to install internet explorer because "it is already installed" even though it is not.

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!

My organization would like to keep automatic updates for Firefox enabled. However, each update prompts end users to create a new profile. We've provided them with instructions on how to navigate to about:Profiles and find the Firefox profile that has their bookmarks. The same set of instructions then guides them on how to save that profile as their default too. Unfortunately, our end users aren't very good at this and sometimes they have to repeat the process for a few days in a row. Which I assume is due to subsequent Firefox updates, but I'm not sure.

That said, is there anything we can do that'd avoid end users from having to go through this process for every Firefox update?
