sir , I have a wordpress website (https://aghortantra.com) Today morning my wp site not opening on mozila firefox but on chrome browser , it opening well. So, I request you please fix the problem.

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 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.

Hello, I am trying to create a deny all & white list only gpo for Firefox extensions.

I am using the gpo; Computer Configuration/Policies/Administrative Templates/Mozilla/Firefox/Extensions/Extension Management

I started out simple using a template which worked.

{ "*": { "blocked_install_message": "Your Company Blocked Message", "installation_mode": "blocked" }, "uBlock0@raymondhill.net": { "installation_mode": "allowed" } }

However, when I tried to add in more allowed extensions it now longer worked and was able to install any extension.

{ "*": { "blocked_install_message": "Your Company Blocked Message", "installation_mode": "blocked" }, "uBlock0@raymondhill.net": { "installation_mode": "allowed" }, "querymoid@kaply.com": { "installation_mode": "allowed" } }

Hi All,

I have recently been enhaciing our security posture and have started sorting out our browser extensions, however I seem to be having errors allowing 2 extensions

• 1Password; and
• Firefox Multi Containers.

This is my json:

{ "*": { "blocked_install_message": "version 0.4 - Addon or Extension is not approved. Please submit a ticket to Help Desk if you need access to this extension.", "install_sources": ["https://addons.mozilla.org/"], "installation_mode": "blocked" }, "{bc8367b6-d946-484e-8da6-37691f23ee64}": { "installation_mode": "allowed", "install_url": "https://addons.mozilla.org/firefox/downloads/latest/1password-x-password-manager/latest.xpi" }, "{2a28e7e4-64c9-4e7f-81fb-0475af840c0f}": { "installation_mode": "allowed", "install_url": "https://addons.mozilla.org/firefox/downloads/latest/multi-account-containers/latest.xpi" } }

I have tried the obvious and removed the {} from both extensions, however still having troubles.

Is someone able to point me in the right direction?

Hello,

We want to run Firefox in our environment which is constantly scanned by a security scanner, and deducts points for applications which have a vulnerability that has an available patch, but the patch has not been installed. These are on shared Windows terminal servers. Firefox is one of two browsers, Edge being the other one.

If users do not launch firefox at least once, then Firefox never gets updated.

Yes, we have the background update service installed, but it sets itself to manual, and if I try to start it, it simply gives the error "error 1: incorrect function"

How can we configure Firefox 115ESR to be able to run this service automatically, check for updates, and install, without a user on a particular terminal server ever having launched the application once?

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.

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.

Good morning,

Can you please answer some questions regarding the Rapid Risk Assessment tool that is available at the following link:

https://infosec.mozilla.org/guidelines/risk/rapid_risk_assessment.html

1. Will any information input into the tool be hosted within the United Kingdom's Servers? 2. Can you please clarify if any information submitted to the RRA toll is retained on your Servers? 3. Is there the option to configure the tool so that no information submitted is retained after the session has terminated.

Kind Regards,

Mark Gormley.

Hello, I have a problem with setting up HTTPs only Mode in my Organization, I read a lot about that, but I dont see the "dom.security.https_only_mode" switch in GPO, we have the newest admx for Firefox. We need that to specific container, but still I dont know how to set it up, even via regedit, or preferences. Can someone describe me when can I set it up ? It could be using json file (which exactly file and how?), registry or just gpo. Regards, M.

Hello,

I'm trying to deploy Firefox with several languages.

I followed the guide on [https://support.mozilla.org/en-US/kb/deploying-firefox-language-packs].

Everything work fine until I set up ExtensionSettings policy. This policy hide and block languages menu.

After scratching my head for a while, I finally figured out how to do it. I would to like to know if an easier way to whitelist all locales and dictionaries. I would like to only control the extensions.

I am trying trying to install the keeper extension via intune but am having trouble with the oma-uri. It looks right to me but I might be missing something. Prior to running this I followed https://mzl.la/3vYAIYT and added the Firefox ADMX. Both run successfully but it does not add the extension. Firefox version 116.0.3

OMA-URI: ./Device/Vendor/MSFT/Policy/Config/Firefox~Policy~firefox~Extensions/ExtensionSettings

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

 "*": {
   "blocked_install_message": Opps, this may have been a mistake reach out to IT.",
   "install_sources":["about:addons","https://addons.mozilla.org/"],

In my environment, we have Firefox version 117. Users get this pop up "You must log in to this network before you can access the Internet" (see snip 1) when they launch firefox. In order to get rid of we can toggle this preference setting to TRUE ""network.captive-portal-service.enabled" in the user's browser, which works fine. But i want to control this setting from GPO. I'm unable to find the GPO for the same in the GPO hive for FF. See snip 2 for 'Preferences' related GPOs.

I'm a security analyst. I would like to get email notifications on security advisories, alerts and vulnerability information regarding Firefox to stay up to date. Please help on how I can get the subscription?

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!

Hello everyone,

being annoyed of a huge amount of Qualys tickets in my enterprise environment, i have decided to use the ability of firefox to update itself on its own instead of deploying a new version each time.

Requirement: Firefox has to stay up-to-date even on devices where it is not used. That´s what the scheduled background update task and Mozilla Maintenance Service are for, right?

Problem: The background update task will only be created if a logged on user will run firefox at least one time. Since Firefox is used as the secondary browser here, it is installed on all clients, but not even half of the clients/users are running it.

I didn´t find any option to create that task manually. So - at least in my environment - the autoupdate mechanism is useless.

Is there any hope for an autoupdate mechanism which can be run independent of logged on users? Or does anyone have an idea how i could achieve my goal?

Thank you in advance!

Dear Team, Our application is accessible on Firefox v101.0.1. But recently we have upgraded our desktops with Firefox v112.0.1. The same application accessible on Firefox 101.0.1 is not able to accessible on v112.0.1.

The error code we could see on browser is SEC_ERROR+PKCS11_GENERAL_ERROR. We have already raised a case with HTTP support team but they have suggested to check at browser level. We had also collected traces from firefox but unable to upload the same. Kindly help here at the earliest. Thanks, Shruti Fegade

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.  :-)

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!

Hi,

We are using Firefox Enterprise on Windows Server 2016 Remote Desktop for approx 100 users.

The users need very often to create a new profile when launching FireFox, and then loose all their bookmarks.

Is there a way to manage the profiles correctly to bypass this problem ?

Thank you for your help ! Have a nice day.
