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.

Version: Firefox ESR 102.9.0 (64-bit) - Windows 10 Enterprise 22H2

Customers have been complaining for about 6 months that they can no longer drag and drop email attachments from Outlook (Microsoft Office Professional Plus 2019 - Exchange) into a Help Desk formula. I tested dragging from Outlook desktop and from the web version.

Drag and Drop works when using Edge and Chrome.

This is not a major issue, since customers can use the other browsers, but since they would prefer to use Firefox, a fix would really be appreciated.  :-)

Environment:

  • Build ID: 20220912135840
  • OS: Windows_NT 10.0 19044

Issue: I had Firefox window 1 opened in virtual desktop 1, then I switched to virtual desktop 2 and open Firefox window 2 there. After using window 2 for some time, I switched back to virtual desktop 1 and found Firefox window 1 was gone. I checked `about:support` page but found no crash report there. I don't know what's going wrong.

What is the proper format for the ExtensionSettings policy registry key/value that is used to manage browser extension settings?

When looking at the ExtensionSettings page for Firefox or Chrome they both use an example that shows the registry key Software\Policies\Mozilla\Firefox\ExtensionSettings (REG_MULTI_SZ) being set to a long JSON string with every extension ID and the settings for that particular ID. For example...

{

 "*": {
   "blocked_install_message": "Custom error message.",
   "install_sources": ["https://yourwebsite.com/*"],
   "installation_mode": "blocked",
   "allowed_types": ["extension"]
 },
 "uBlock0@raymondhill.net": {
   "installation_mode": "force_installed",
   "install_url": "https://addons.mozilla.org/firefox/downloads/latest/ublock-origin/latest.xpi"
 },
 "https-everywhere@eff.org": {
   "installation_mode": "allowed"
 }

}

The problem with this method is that if I am installing an extension, and I overwrite what already exists in Software\Policies\Mozilla\Firefox\ExtensionSettings then all of those other settings get removed. So even if I am a non-malicious actor and just make a mistake with my installer I can easily delete every other extension's settings. Instead what I have to do is during install I have to read the current value of Software\Policies\Mozilla\Firefox\ExtensionSettings and then insert my extension's settings into the JSON blob.

So the examples that Firefox and Chrome provides do of course work, however they do not make very much sense to me. Why would it be formatted this way since all of those are additional key/value pairs and that is exactly what the registry excels at storing. So why put all of those into a single key/value instead of breaking them into multiple?

Additionally breaking them a part into multiple key/value pairs does work! So if instead of the example above I were to split them into multiple key value pairs it works just fine!

Software\Policies\Mozilla\Firefox\ExtensionSettings

   uBlock0@raymondhill.net
       "installation_mode": "force_installed",
       "install_url": "https://addons.mozilla.org/firefox/downloads/latest/ublock-origin/latest.xpi"

So knowing that this way with multiple key/value pairs works why am I bothering to ask this question at all instead of just doing it the way that makes sense to me? Well the issue is that by breaking it up into multiple key value pairs it actually overrides the other method and makes it so that all those registry settings are ignored. So it doesn't delete them but it still leaves me with nearly the exact same problem.

While I believe "my" way is superior because it uses the registry in a more common sense route, if that is not what the majority of extension developers do then it doesn't matter and I should be conforming to the other way.

As I am typing this question up I did realize just how hard/annoying it is to properly format and make it clear and digestible what the multi key/value format of the registry would look like instead of being a JSON string. So perhaps that is the reason why all the documentation puts it all as one JSON string?

One of our vendors websites does not load under Firefox ESR, with errors in the console pointing to CSP. Error is: Content Security Policy: The page's settings blocked the loading of a resource at inline ("default-src")

However if I load the site under the normal Firefox release, it displays correctly. When looking at errors in console, it is showing 3 errors for CSP, however it does not stop the site from working correctly. Content-Security-Policy: The page's settings blocked the loading of a resources at https://..... ("connect-src") or ("img-src")

The site is https://app.approvalmax.com If you get the login screen then the site is working otherwise just getting a green background when it is not working.

I am unsure why ESR and RR versions are behaving differently in this case. Using the latest versions of each.

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.

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?

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.

Hi everyone. I have installed Firefox on all windows 10 workstations and I have also installed latest Firefox Group Policy ADMX on Server. I need to set some preferences on all Workstations. The preferences that I want to set are the ones that can be found in about:config.

But the problem is that only some of these preferences exist in Group Policy by default and it says "deprecated". I know that I can add additional about:config preferences in a Group Policy object called "Preferences". But no matter how I enter the format or how I change the JASON file, no preference policy is applied to Firefox in workstations. By the way when I change "Preferences" gpo in group Policy the next Policy called "Preferences (JASON on one file)" does also change. I have thoroughly searched the web and Mozilla support and have tested all suggestions but all to no avail. Can you please help me and Give me an example of how to do that? I would appreciate any answer in advance.

Hello I have installed german Firefox Version 117.0 (Build-ID 20230824132758) on Windows 10.

The following ExtensionSettings policy works as expected. The addons ublock and TreeTabs are both installed automatically.

   "install_url": "https://addons.mozilla.org/firefox/downloads/latest/tree-tabs/latest.xpi"

}


But I don't want TreeTabs to be installed automatically on all workstations. So I want to change installation_mode to allowed.


{

}


But with this setting I'm unable to install it manually from https://addons.mozilla.org/de/firefox/addon/tree-tabs/ The message "An unexpected error occurred during installation." and a popup with the "blocked_install_message" "My Message" is displayed.

The same error occurs without the line (and the comma) "install_url": "https://addons.mozilla.org/firefox/downloads/latest/tree-tabs/latest.xpi"

I don't know why this does not work. Please help. Thank you.
