Hello,

I have a plug-in installed on multiple machines using group policy. The installation source is a link to <my_add_on.xpi>. My question is regarding the updates approach. If I replace the source file with an updated version, but keeping the name/link the same. Will Firefox automatically update the plug-in? Only found brief docs here: https://github.com/mozilla/policy-templates/blob/master/README.md#extensionsettings """

If you need to update the extension, you can change the name of the extension and it will be automatically updated. Extensions installed from file URLs will additional be updated when their internal version changes.

""" I don't point to a local file, but rather a URL. Does that make a difference. Or I'll have to provide the updates.json in the plug-in manifest that points to the latest version?

Thank you.

Hello, I am trying to manage extensions in my organization. What would be the best way to block all extensions by default and allow only certain specific extensions?

I am following the Mac OS Extension Settings Policy and adding this to a configuration profile, but I am not sure how to manipulate it to suit my needs.

What would be the best way to go about this, and what would the plist file look like?

Thanks!

Hello Guys,

in our network we have several Fritzbox Routers which we remote administrate. If we connect to the routers with Firefox V115.2.0 we get a warning message - because it´s a Fritzbox self-signed certificate and cannot be validated. No Problem - everything okay with the message. But in Firefox 115.2.0 there is no advanced button that lets you go futher to connect to the website. With Version 102.14.0 ESR the advanced button is there. The webinterface works fine with Edge and Chrome (with warning but with advanced button to continue)

Is this a bug?

I have seen many references to this problem that Mozilla does not seem to want to fix.

I have to log in to my (remote) server regulary using the server IP address - there is not a domain name.

Every time (cookies/history always cleared on exit) it presents the message "Warning: Potential Security Risk Ahead" and then have to click advanced then accept the risk. Under previous versions I use, this could be stored so you do not have to go thrugh this process EVERY time on logging in to the server.

Everyone knows you can NOT assign a security certificate to an IP address so why does Mozilla not take this into consideration?

Will they change this in future versions?

Is there a work around (no config changes seem to work or chrome changes)

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.

{

 "*": {
   "blocked_install_message": "My Message",
   "install_sources": ["https://addons.mozilla.org/"],
   "installation_mode": "blocked",
   "allowed_types": ["locale", "extension"]
 },
 "uBlock0@raymondhill.net": {
   "installation_mode": "force_installed",
   "install_url": "https://addons.mozilla.org/firefox/downloads/latest/ublock-origin/latest.xpi",
   "default_area": "navbar"
 },
 "TreeTabs@jagiello.it": {
   "installation_mode": "force_installed",
   "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.

{

 "*": {
   "blocked_install_message": "My Message",
   "install_sources": ["https://addons.mozilla.org/"],
   "installation_mode": "blocked",
   "allowed_types": ["locale", "extension"]
 },
 "uBlock0@raymondhill.net": {
   "installation_mode": "force_installed",
   "install_url": "https://addons.mozilla.org/firefox/downloads/latest/ublock-origin/latest.xpi",
   "default_area": "navbar"
 },
 "TreeTabs@jagiello.it": {
   "installation_mode": "allowed",
   "install_url": "https://addons.mozilla.org/firefox/downloads/latest/tree-tabs/latest.xpi"
 }

}

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.

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.

Dears, Based on your documentation on https://github.com/mozilla/policy-templates/blob/master/README.md#extensionsettings I am not able to successfully deliver setting to firefox app via Intune OMA-URI. Can you check this on your side and help?

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!

Hi there,

I'm playing with policies.json on Linux/Ubuntu now, trying to improve my knowledge of Firefox customization through different policies and user interaction after the Firefox deployment. I added a custom bookmark and extension, which show and install okay when I restart the browser. But when I delete them from within the browser and restart Firefox, they show up again. To avoid this, I can delete /etc/firefox/policies/policies.json after the Firefox deployment. Hence my questions:

• Is the deletion of the JSON file after the Firefox deployment a reasonable option at all?
• If yes, how can I automate the process silently, without user interaction?
• If no, what would be your advice to let users modify the browser settings like removing extension(s) or bookmark(s) set in policies.json so that they do not reappear after the browser restart?

Thank you! Rustam

Are these supposed to look different, or am I just doing something wrong? In the image I included here, SanitizeOnShutdown and Preferences look different from FirefoxHome and look incorrect. I removed other policies to make this simpler, but all of the other policies with multiple policy values look just like FirefoxHome. It appears that SanitizeOnShutdown is at least working since my history is indeed getting cleared on shutdown, but I'm unsure whether this actually works when I set these to the settings they should be since they should all be false other than Locked. Am I doing something wrong here or are these two policies supposed to look like that for some reason? Thank you in advance for the help!

I am using the intune preview feature which allows you to import admx/adml instead of using the custom injection method. Everything works far better then with the injection method, except for one settings:

ExtensionSettings this setting is working when I have only one setting set (ex):

{"someplugin@test.com": { "installation_mode" : "allowed" }}

If I add a second line to the entry:

{"someotherplugin@test.com":{ "installation_mode" : "allowed"}}

I understand this is a new feature, but if I had the correct format that would work for HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox\ExtensionSettings to allow two plugins to work I belive I shouldn't have any issue getting the admx feature to do this, I even tried manually editing the registry setting and it breaks whenever I add the second line to it.

I have one extension to be installed on the enterprise network machines. There are host permissions required to access All websites data. How can I, as an Admin, enable this host permissions for the installation ?

I recently deployed Mozilla Firefox 102.4 ESR here in our environment expecting that when a new version is released Firefox would automatically update on clients computers. Well today I noticed at a new release is out but isn't automatically updating on end users workstations. Does Firefox ESR not automatically update?

Hello,

I am working to convert my Org to Firefox ESR, but in order to this I need to uninstall the per user install of Firefox. We have many users that have the Firefox.exe located in their Local Appdata folder. So I need to test the uninstall of the Appdata install and then the install of ESR. But the problem is I haven't been able to get Firefox to automatically install into the appdata folder. How am I able to do this? The users who have it installed in the appdata folder are not admins on their computers. When I'm testing I've also been using a normal user account. Please let me know how I can install the exe into the appdata folder automatically without me specifically placing it there or which exe version I need to do this.

Thanks!

We would like to install a custom search engine using Firefox policies. We have the latest version of Firefox installed. We have the latest admx files installed on our Domain Controllers. In the Policy, I go into the User -> Administrative Templates -> Mozilla -> Search and setup a search engine using Search Engine One. I then go into Default Search Engine and configure our custom search to be default. What we find is that the custom search engine never installs, so the custom search engine is not set at the default. If I manually add the custom search engine using the Search Engine Helper Add-on, I can verify that the custom search settings do indeed work. With that said, does anyone have thoughts on how to troubleshoot this issue? First, need to figure out why the custom engine isn't installing at all. Thanks.

Hello,

We have a vulnerability scanner in our environment that tells us when Firefox needs to be updated. We found that in order to update it, we need to go the settings tab and then to the updates portion of the menu to initiate the update. After this we are asked to restart. Any way to avoid this entire process?

Can we set up these gpo`s so that there is a check for dependencies?

Windows (GPO)

Software\Policies\Mozilla\Firefox\SecurityDevices\Add\NAME_OF_DEVICE_TO_ADD = PATH_TO_LIBRARY_FOR_DEVICE Software\Policies\Mozilla\Firefox\SecurityDevices\Remove\1 = NAME_OF_DEVICE_TO_REMOVE

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?
