Can no longer play media with Firefox ESR 102.x

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.

Dear Everyone, Facing issue with deploying Configuration Profile for Extension Settings via Intune. Tried ADMX imported template with adding there "block all extensions" and allow certain ones. Worked perfect in Jamf, for Intune failing all time. We are using Firefox v.121, policies are for v.120, but I am in doubt that this is the issue. Can someone review and let me know if there any issue or may be changes? Using latest instructions https://mozilla.github.io/policy-templates/#extensionsettings Also here is my OMA, very easy.

OMA used ./Device/Vendor/MSFT/Policy/Config/Firefox~Policy~firefox~Extensions/ExtensionSettings

Value(string):

<enabled/> <data id="ExtensionSettings" value=' {

 "*": {
   "blocked_install_message": "Security Test",
   "installation_mode": "blocked",
   "allowed_types": ["extension"]
 },

   "installation_mode": "force_installed",
   "install_url": "https://addons.mozilla.org/firefox/downloads/latest/zoom-new-scheduler/latest.xpi"
 },
   "@react-devtools": {
   "installation_mode": "allowed"
 }

}'/>

Good morning,

I'm reaching out to see if I can get some assistance with Firefox on of our network. I'm System Admin at Goodfellow AFB. I've tried searching this issues on the web and found similar issues but solutions that were recommend online have not worked for us. Yes I have uninstalled Firefox completely and installed it from scratch. I know it has something to do with autoconfig file but not sure what exactly I'm looking for. Thanks.

deploying firefox-add-ons via group policies doesn't work anymore after proxy-change

Hello, I used to deploy add-ons via group policies - this worked like a charm: Firefox esr (91.11.0esr x64), ADMX-templates in Sysvol\PolicyDefinitions, Group Policies: … (read more)

Hello,

I used to deploy add-ons via group policies - this worked like a charm: Firefox esr (91.11.0esr x64), ADMX-templates in Sysvol\PolicyDefinitions, Group Policies: User configuration, administrative templates, mozilla, firefox, add-ons --> install add-ons --> https://addons.mozilla.org/firefox/downloads/file/1234567/goodaddon-1.0.01.xpi

A few months ago, we had to change our network-configuration. We were using a proxy before, but our proxy had direct access to the internet. Now our proxy forwards everything to another proxy. Since about that time, add-on-deployment via gpo doesn't work anymore. It could be something else, but i suspect the proxy-change.

I tried to deploy unc-paths, internal websites and different syntaxes; none of this works:

  • http://192.168.100.10/goodaddon-1.0.01.xpi
  • http://internalwebsite/goodaddon-1.0.01.xpi
  • https://192.168.100.10/goodaddon-1.0.01.xpi
  • https://internalwebsite/goodaddon-1.0.01.xpi
  • \\192.168.100.20\netshare\goodaddon-1.0.01.xpi
  • \\internalfileserver\netshare\goodaddon-1.0.01.xpi
  • file://///192.168.100.20/netshare/goodaddon-1.0.01.xpi
  • file://///internalfileserver/netshare/goodaddon-1.0.01.xpi

As you can see I tried using internal sites, so that no proxy would be needed. And I also added these sites to the allowed add-on-installation-sites (computer configuration, same group policy). The sites are all accessible; if I enter these addresses as url, firefox can access the xpi-file.

I know how to pack add-ons into the firefox-setup-file; that still works. But first of all, firefox is already installed on most of my clients. Second, after a fresh installation of firefox with this self-created package, all add-ons are installed, but not activated. And I would like to restrict activation/deactivation of add-ons via gpo.

  1. 1 Are there other ways to deploy add-ons in a domain-network (e.g. script-based)?
  2. 2 Are there any logs where I could find out what exactly goes wrong?
  3. 3 Are there any other syntaxes I could try (group policy urls)?
  4. 4 Can anyone guess what the problem is (why it is not working anymore)?

Help would be very much appreciated.

Best regards.

Hello, Qualys is detecting Vulnerabilites on our Firefox ESR 91.12 Versions which were patched by MFSA2022-29.

It is showing Vulnerabilities because MFSA2022-30 lists CVE's for ESR 102.X and we are on 91.12.

Is there anywhere I can go to get a list of all Vulnerabilities on 91.X to show our Security team, I believe CVE-2022-36314 and CVE-2022-2505 are not present in 91.12 because they are not listed in https://www.mozilla.org/en-US/security/advisories/mfsa2022-29/ but need evidence

Intune ExtensionSettings Policy No Longer Working in Firefox

Hello, in Firefox browser, my organization has always blocked all extensions except for ones we allow through OMA-URI ./Device/Vendor/MSFT/Policy/Config/Firefox~Policy~firefox~Extensions/ExtensionSettings.

About a month ago this stopped working and our end users can now install any extension in the Firefox browser that they choose, without approval, creating a security risk.

When checking in about:policies, there is a policy error: Unable to parse JSON for ExtensionSettings. We have checked with Microsoft Intune support and they verified that the policy looks to be configured and targeted correctly.

Here is a snippet of our JSON, this is a test policy where microsoft support had us remove "about:addons" from the 'install sources'. Both test and production policies are not working.

<enabled/>
<data id="ExtensionSettings" value='
{
    "*": {
        "blocked_install_message": "Contact Service Line",

    },
    "linkedinConverted@firefox-extension": {

    },
    "jid1-93WyvpgvxzGATw@jetpack": {
        "installation_mode": "allowed"
    },

Is this a bug? Or something wrong with our configuration? Has firefox changed the requirements of the extensionsettings OMA-URI?

Thanks for any help in advance.

We downloaded the GPO Templates for AD and looking to customize Firefox.

We would like to disable Forms and Autofill: Autofill addresses Autofill credit cards

Also would like to lock down so they can't reenable if possible.

We would like to do this all through GPOs if possible. I found these in the about:config: extensions.formautofill.addresses.enabled extensions.formautofill.creditCards.enabled

But again want to do through the GPO. Is this possible?

Side note while working on GPOs, I set Exceptions for the popup blocker and they are not showing up in the browser. I also filled out to remove Search Engines but they all still appear in the browsers. These two GPO settings don't appear to be working.

Hi,

We've GPOs in place for Edge and Chrome that set said browsers on all our Windows endpoints to open downloaded ICA files in Citrix Workspace.

I've imported the firefox.admx and mozilla.admx file along with assocaited .adml files, checked Github, checked through the GPO settings yet cannot figure out how to do the same with Firefox.

Is there a Mozila Firefox for Windows GPO ADMX setting I can use to control the "Firefox>Settings>General>Files and Applications>Applications" section to add "Content type: ica | Action: Use Citrix Workspace"?

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!

We use Microsoft MDT for computer deployment. We have been installing the Standard version of Firefox for a long time with no problem. Recently we started using AD GPO Templates to configure firefox. To be able to configure certain settings you need to be running the ESR version. I downloaded the more recent ESR version: 102.12.0esr.msi file.

When deploying machine MDT to install Mozilla firefox I keep getting this error: Application Mozilla Firefox ESR returned an unexpected return code: 1618

This is the only application having issues and this issue only came up since I change the installation file to the ESR version.

This is the install command being used in MDT: msiexec /i "Firefoxesr.msi" /qn /norestart

I am posting here and not with MDT support, as this only started happening when I changed the installation file to the ESR version. Has anybody else had a problem deploying ESR version through MDT? Any help on how to fix?

I need to set the max TLS version to 1.3 and the min version to 1.2 on my shstems. The max and min TLS versions are set to 4 and 3 by default in about:config. If I use lockPref(“security.tls.version.max”,”3”), it is still 4 in about:config for some reason. If I set the min version to 2, it is still 3. This also doesn’t work if I use “SSLVersionMin”: “tls1.2” how can I fix this issue? Thank you in advance!

Hello,

I want to download an extension using firefox policy templates. I put the location folder and extension id so that it cannot be deleted, but for some reason it doesn't want to install most of the times. The policy is added after using the gpupdate /force command and restarting the machine then open and close the browser. I wait 10 minutes for the policy to be configured on the computer and open the browser again and nothing happens. Also, the keys in the registry have the corresponding value type (checked in site https://admx.help/?Category=Firefox&Policy=Mozilla.Policies.Firefox::Extensions_Locked). But when I drag and drop with a mouse, the extension is installed and cannot be deleted. Can you tell me why does the extension not install when the policy is in effect?

I sent pictures from Group Policy Manager, Registry editor and showing that the extension can not be deleted after drag and drop with a mouse.

Thank you in advanced!

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

I am looking for information regarding the support life for settings that are defined in the Preferences (Deprecated) section of the ADMX templates provided in GitHub. There doesn't appear to be a definitive answer as to when these preferences are no longer applicable to a version of Firefox. The term "Deprecated" certainly applies they're on their way to extinction. But only a small handful of preferences have been ported over to non-deprecated template settings (like Auto Update). Is there an expected version of Firefox where all these preferences are meaningless? Or will they be supported indefinitely? "Industry recommendations' from 3rd party security vendors are bloating my policies in the domain space and I can't definitively say they are 'no longer supported as of version xyz' for all these Firefox Preference settings, which happen to be about 80% of the security parameters defined by STIG and/or CIS Workbench.

I am installing Firefox via microsoft endpoint, and deploying multi account containers with the OMA-URI policy for extensions. (this blog page is super helpful! https://securitygeneralist.blogspot.com/2019/08/auto-installing-extensions-on-firefox.html )

The extension by default has containers for Personal, Work, Banking, Shopping.

Is there a way to automatically remove that default container list as part of the install?

Even better, is there a way to create a different default containers list through Endpoint?

Thanks

Hi!

Using Intune, we are setting some settings in Firefox. One that is a bit troublesome is the ExtensionSettings

Currently looks like this:

{

 "*": {
   "blocked_install_message": "Blocked.",
   "installation_mode": "blocked"
 },
 "uBlock0@raymondhill.net": {
   "installation_mode": "allowed"
 },
 "addon@darkreader.org": {
   "installation_mode": "allowed"
 },
 "@react-devtools": {
   "installation_mode": "allowed"
 }

}

I get the Blocked message if I try any of the allowed extentions like uBlock, Dark Reader or React Dev Tools.

I can add that uBlock had "force_installed" (With URL since that is required for force) and that worked fine.
