Firefox 企业版 支持论坛

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.

I keep getting this error. I reinstalled mozila firefox esr, but the error seems to persist. What could I do to get rid of this error that constantly appears at a certain time interval?

We followed the links below to block internet access in Firefox browser:

https://www.youtube.com/watch?v=fAGYYX5hYb8 https://github.com/mozilla/policy-templates/releases

We downloaded the ADMX and ADML files. Using these files, we were able to locate Mozilla Firefox in Group Policy Management and successfully block all websites in the Firefox browser using the pattern :///*.

However, we encountered an issue with exceptions. We do not wish to block certain websites, including localhost. We attempted to use the "Exceptions to block websites" option, providing values such as ://msn.com/ to exclude specific sites. Unfortunately, this approach did not work as intended. For instance, msn.com is one of the websites we want to allow, among others and also localhost.

We require assistance with the following issue: "Exceptions to block websites" is not functioning properly within the group policy of Mozilla Firefox.

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.

Welcome, We are implementing redirected folders in our company via Widnows Server. We are also redirecting the Appdata folder. We have offline mode enabled which means that the folders are synchronised every 5 minutes. The synchronised Appdata folder has a Firefox profile which causes a lot of conflicts. Every time the folder is synced there are conflicts like "Both versions have been updated since the last sync" or "Cannot sync now. Try again". I attach a screen shot of how much of this there is. No other applications cause such errors. Only Firefox blocks us from a large deployment. If the problem cannot be resolved we will be forced to abandon the FireFox browser altogether. Has anyone had a similar problem?

Attempting to disable FF Password manager completely for my org via a plist.

Currently have the password manager itself disabled but can't figure out how to disable the Auto-fill settings with previously saved passwords prior to the password manager being disabled?

Is this possible? Or is this disabled already when the password manager itself is disabled?

Currently have this set via a plist:

<key>PasswordManagerEnabled</key> <false/>

Hi there,

We are currently utilizing Windows Server 2019 as our development server. To maintain security protocols, we have implemented a Group Policy to block internet access on this server. Initially, this configuration successfully restricted internet access on all browsers, including Firefox. However, recently we encountered an issue where internet access became available solely through the Firefox browser, posing a significant data security risk.

Upon investigation, we discovered that Firefox allows users to modify proxy settings, effectively bypassing our Group Policy restrictions. Unlike other browsers, Firefox permits users to adjust proxy settings without sufficient rights, thus overriding our established restrictions.

To mitigate this issue, we require guidance on enforcing Group Policy settings within Firefox to prevent unauthorized alterations to proxy settings and ensure internet access remains restricted. It's important to note that Firefox is exclusively utilized for development purposes on our server.

Your assistance in resolving this matter would be greatly appreciated.

Regards, Hiten

Is there a way to trigger a Firefox browser update through command line or script? I need to trigger an update across a few hundered computers and I can do this, but through command line or script automation. What is the command line syntax to do this, if there is any?

Thank you for your help

During a client Audit earlier this week we were dinged on not having the option in Firefox ESR to block manually saving Addresses and Credit Cards. We have the autofill disabled however users can still manually add credit cards and addresses and this poses an issue with our call center agents handling Credit Card info. I'd like to be able to gray out the Saved Addresses and Saved Credit Card boxes so as to prevent agents from manually entering card data into it using a GPO or Registry setting that we can push and apply to all our domain PCs. Ideally, if we could add an entry to the JSON preferences in the Mozilla GPO that would gray those options out that'd be best but any option that removes the users ability to add CC info would be acceptable.

I'm looking to allow the CyberArk extension for FireFox, via our GPO. I am not seeing the application ID for the extension, which is needed.

I'm hoping that you folks can provide that ID.

Thanks!

Hi All, I have been on the struggle bus lately trying to get the application handlers set properly in our GPO. I am trying to get PDF, webp, avif to open in browser, and jnlp to auto launch Java. Any help will be greatly appreciated!

{"application/pdf":{"action":3,"extensions":["pdf"]},"image/webp":{"action":3,"extensions":["webp"]},"image/avif":{"action":3,"extensions":["avif"]},"application/x-java-jnlp-file":{"action":4,"handlers":[{"name":"javaws.exe","path":"C:\\Program Files (x86)\\Java\\jre-1.8\\bin\\javaws.exe"}],"extensions":["jnlp"]}}

HI Team,

I am working for an organization, members have different versions installed and need help to uninstall the Firefox completely, Member able to see the application installed in Apps and features and but files do not exist in program files or program files x86, please someone please contact me for my queries [removed phone# from support forum]. my email id [edited] @gmail.com

The script is not removing the application

IF EXIST "%ProgramFiles%\Mozilla Firefox\" ( "%ProgramFiles%\Mozilla Firefox\uninstall\helper.exe" /s )

IF EXIST "%Program Files (x86)%\Mozilla Firefox\" ( "%Program Files (x86)%\Mozilla Firefox\uninstall\helper.exe" /s )

How can I apply a policy based on "blocked_permissions". I've read Chrome documentation but I guess Firefox does not support this parameter. Right? If so, is there any way to request this feature?

I need a policy like

{

 "policies": {
   "ExtensionSettings": {
     "*": {
       "blocked_permissions": ["tabs"]
     }
   }
 }

}

I need to be able to hide the Extensions button from the toolbar. Is there a way to do that outside of the user.js or prefs.js? Preferably I'd like to do this though the policies.json file though I could not find any options for this.

I would like to prevent users to navigate on the Linux system when they view a PDF and then use the Save option. The "PDFjs" policy enables or disables the PDF Viewer but does not control the built-in PDF Viewer menus.

I have imported the ADMX and tried to add an extension but it does not appear. So I imported the admx and this is working because I have another custom oma-uri that sets the home pages.

Here is what I have for my custom oma-uri to try and get the 1password extension added to FireFox. It is coming back with an error, Any recommendations? Name: Extensions_Install OMA-URI: ./Device/Vendor/MSFT/Policy/Config/Firefox~Policy~firefox~Extensions/Extensions_Install Data Type: String Value: <enabled/> <data id=”Extensions” value=”1\https://addons.mozilla.org/en-US/firefox/addon/1password-x-password-manager”/>

Looking to specify homepage, homepage button, and new tab page within Firefox on our Mac fleet.

I was able to create a plist file for macs, and it was "deployed successfully" according to Intune, but no changes actually happened on my test machines.

I've uploaded a redacted version of the used plist.

Anyone out there have any ideas?

Dear Forum,

Maybe this has been already asked but i keep getting the quite opposite when searching.

is there a way that i can save passwords, for autofill purposes, for specific websites in Firefox using GPO?.

I have 4 computers, that are currently deployed with Firefox and all 4 should be able to login to a specific website with a given username and password. I would like to set the username and password for them stored in the Firefox password manager and let it autofill it for them when going to the given website.

Or should i do this using the created shortcut they received, deployed to their systems using GPO?

Thank you in advanced.
