Firefox Enterprise Community Forum

I have Mozilla Firefox and Mozilla ESR browsers updates to manage across the devices. Policies have been configured on browser from Intune and same has been reflected everywhere in registry, and update.json file. still task is missing. can someone help on this. Also i have few ESR so will same ADMX file will work for that?

Hi all,

We use a service integration in our organization that only works in the latest ESR version of Firefox (140.14). The latest regular release breaks our integration due to added security policies preventing the software from communicating with Windows services.

After installing the ESR version and disabling auto updates in the settings and adding the DisableAppUpdate registry key, the software still keeps updating to 154 (not the ESR version). I've also chosen to not install the Mozilla Maintenance service when installing the ESR version. I can't seem to find any support articles of people having the same issue. Is there something I may be missing? Any help would be greatly appreciated.

Hello, we have the issue, that Firefox esr 153.1.0 crashes on opening urls. The crashes happen on several devices. These are the current crash-reports: bp-3e6bd41b-89b0-4a49-9479-90cbc0260831 bp-9bd858e0-2573-4a01-8bac-90c320260831 bp-ad358921-a24d-4e02-9ed5-2bc4d0260831 bp-0bfb15d0-b637-48b6-a445-94b350260831 bp-0dc0dbcb-fb77-4ce6-a1c0-659f40260831 bp-268bf05a-3eb7-493e-bd40-42e0c0260831 bp-3910ddb1-9dbd-4016-b421-0dd450260831

thanks for Help and advice.

Best Regards

Hi,

In the latest firefox update 154, no start pages are displayed that were distributed with a registry key via group policy. It only works again if you change this setting manually in the Firefox settings.

In Version 153 it´s fine.

Hallo, my setup is some server (keycloak) with mTLS needing keypairs just for allowance for the machines in the enterprise. But as far as i know, i need to setup personal keypairs for the users, not just the machines. How do i push a ".p12" keypair into the browsers trust stores? Is there a way via GPOs? As far as i have read the https://firefox-admin-docs.mozilla.org/reference/policies/, there is no support for ".p12" files?

The only way i got told from AI is via a script. If i could just stuff that ".p12" file into some place in the GPO, i would be perfectly happy... (?)

I don't understand why auto:config is so difficult (for me at least) to create. Isn't there an easier way? I've tried following the directions and creating the 2 files. But I can't manage to successfully create auto:config.

I created and pasted the first tile into the prefs folder. For the 2nd, I noticed the firefox.cfg file I created in Notepad appended a .txt suffix. I pasted it into the Firefox top directory. Then typed auto:config into the address bar. Nothing happened. Can anyone tell what I did wrong? Is the .txt suffix not recognized? Or is there's an easier way to do this?

We are managing Firefox settings using Intune via Imported ADMX templates.

We are managing Extension Settings via 'Extension Management (JSON on one line)' which works fine for our force installs, force removals etc.

We have noticed that some users have installed 3rd party extensions which create the ExtensionSettings key in the registry with the 3rd party extension details.

The issue we see if when ExtensionSettings exists as a REG_SZ or REG_MULTI_SZ under `HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox` it is then ignored if the `HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox\ExtensionSettings` key exists.

Is there a setting we can use to have these settings merged by Firefox or have the REG_SZ/REG_MULTI_SZ take priority or is the only way to ensure enterprise policy continues to work we need to migrate our extension settings into the key rather than string?

Thanks!

I'm trying to get the Enterprise Release Notes for Firefox 148 and 149. They seem to be the only ones missing from 141 to 151 inclusive. It appears the URL for the notes is in the format https://support.mozilla.org/en-US/kb/firefox-enterprise-###-release-notes/, where ### is the version. For these two versions, I get a "Page Not Found" error.

I have tried finding them through the Firefox Release Calendar (https://whattrainisitnow.com/calendar/). If you click on the link to expand previous releases and then click on a release version number, the page that comes up has links to the three different versions of release notes. Enterprise shows a link for the two missing versions in the same format as I have noted above.

I have also tried https://support.mozilla.org/en-US/products/firefox-enterprise/whats-new-firefox-enterprise and it lists quite a few versions but 148 and 149 are missing in action.

we are using firefox std version in more than 15000 machines in our organisation, recentlty we migrated to all machines to ESR version, but now we are getting escallation, the application working very slow and not opening sometimes

I don't know if feature requests should be made here or elsewhere, but both chrome & edge have policies to force safe search in google (and bing in edge) in addition to a policy to force restricted mode in youtube, so I wish these get added to firefox.

Also, there is no policy to block firefox task manager (about:processes). I don't know if it's a security vulnerability to add it or not.

Is there a blessed solution to the problem above? I'm sure we're not alone, but our end users are not admins. God forbid... So the official statement of "enter admin credentials" is not a plausable solution on managed systems. Providing a Reinstall Firefox on the users' selv service store is something we can do, but users are usually not fond of losing browser data. (I do konw about Firefox account to sync/restore) My question is more like as the problem roots back to permission problems, what would be the proper command(s) to fix permissions? I can run commands on the end users' comptuers in the background, as root/system user, or even as them of course. Thanks

Hello,

I had seen this topic : https://support.mozilla.org/en-US/questions/1489702, i'am using a GPO to deploy an Lockself (password manager) extension on Firefox 152 on all computers in my company. I wanted to pin to navbar just this extension, because users will ask at first time where is it. I have changed the JSON to pin to navbar :

{

 "{ca613ee6-4211-4ae2-aa3c-d29608461d11}": {
   "installation_mode": "force_installed",
   "install_url": "https://addons.mozilla.org/firefox/downloads/latest/lockself-password-manager/latest.xpi",
   "updates_disabled": false,
   "default_area": navbar
 }

}

But when i reload the GPO on a test machine this GPO isn't applied.

So it seems the bug isn't solved ?

Thanks

Hi all,

Firefox 140.10.2esr Windows 11

Opened Firefox this morning and it said I was using an old version of Firefox and it couldn't load my profile. I have always used the esr version.

I had a look at the compatibility.ini file under my profile and it had version 150.xx. Is that a bug with the last update?

To recover I backed up my profile then changed the compatibility version to the version of Firefox I am using. I was able to load my profile and while all my bookmarks and settings are there, my saved credentials are not. The key4.db and logins.json file are both still under my profile folder, they just don't seem to be recognised; no errors. Viewing the logins.json shows my encrypted credentials.

Does anyone know what is going on and how to resolve?

thanks
