Firefox za Enterprise Community Forum

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

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.

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 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,

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.

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.

Hi everyone, I'm trying to standardize the homepage for the browser which enrolled with Intune on MacOS. I have imported the .plist file as below with the preference domain name as "org.mozilla.firefox". After applied, it returned error and nothing has been changed on the browser. Thanks.

<key>Homepage</key> <key>URL</key> <string>http://example.com</string> <key>StartPage</key> <string>homepage</string>

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.

Need way to overwrite prefs.js with corporate standard for kiosk like environment. Either need way to have firefox install in standard path within each user profile or have firefox insert file from source. Advice ? thanks.

Nessus, Qualys, IBM Big Fix security scans constantly pick up firefox vulnerabilities. What we find is that either users have deleted the Firefox background update task or on servers, it never gets put onto the task scheduler. All other browsers have a channel update in the GPO files that ensure they are kept up to date and never show up in our scans. When will firefox put out similar channel GPOs and quit relying on the differently named task that we can't put into a group policy task scheduler, but constantly find firefox vulnerabilities from users that have deleted it so that group policy does not take effect.

I'm trying to configure the "Extension Management" policy for firefox in my company. We have 14 addons to manage. using JSON this will end to a line of about 2500 characters.

when I try to copy the code into the gpo I get a message telling me the limit is 2048 characters.

Is there a way to baypass this limitation ?

thank you

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,

McB

I have a need to use regular browser (not kiosk), but disable the "open downloads folder" once a file has been downloaded. This is opening a file manager (thunar or alike) which then allows the user to browse the filesystem and open a terminal emulator from /usr/bin.

Using the policies, I am able to prompt for downloads, or select a download location, however I have been unable to completely stop the user from opening the download folder which opens a file browser.

Is there any way I can select policies or profile options for disabling the option for opening download folder?

From my point of view, the setting " What should Firefox do with other files?" has been added in the current ESR version.

"What should Firefox do with other files?" ("Wie soll Firefox mit anderen Dateien verfahren?") . "Save files" ("Dateien speichern") . "Ask whether to open or save files" ("Fragen, ob Dateien geöffnet oder gespeichert werden sollen")

How can I control/change this setting using mozilla.cfg?

By the way:

// What should Firefox do with other files? - Wie soll Firefox mit anderen Dateien verfahren? lockPref("applications-ask-before-handling", false);

// What should Firefox do with other files? - Wie soll Firefox mit anderen Dateien verfahren? lockPref("applications-ask-before-handling", true);

works detectably via about:config but does not change the setting for "What should Firefox do with other files?".

OMA-URI:

./Device/Vendor/MSFT/Policy/Config/Firefox~Policy~firefox/Proxy Value (string):

<enabled/> <data id="ProxyLocked" value="true | false"/> <data id="ConnectionType" value="none | system | manual | autoDetect | autoConfig"/> <data id="HTTPProxy" value="https://httpproxy.example.com"/> <data id="UseHTTPProxyForAllProtocols" value="true | false"/> <data id="SSLProxy" value="https://sslproxy.example.com"/> <data id="FTPProxy" value="https://ftpproxy.example.com"/> <data id="SOCKSProxy" value="https://socksproxy.example.com"/> <data id="SOCKSVersion" value="4 | 5"/> <data id="AutoConfigURL" value="URL_TO_AUTOCONFIG"/> <data id="Passthrough" value="<local>" >="" <data="" <="" p=""></data>

This has mixure of String and Integer , when we configure as string and use one from the above or leaving blank or setting only string , it failed the policy with error - -2016281112
