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"]
     }
   }
 }

}

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.

We are currently looking at devices with out-of-date Firefox versions these are listed with vulnerabilities within our environment and need to be patched to the latest version to cover those vulnerabilities.

With the volume of patching required, we want to be able to enable auto-update and allow the application to patch itself.

However, the current options via group policy don't seem to work as I've read on such threads https://bugzilla.mozilla.org/show_bug.cgi?id=1876302.

The application Autoupdate has been enabled within local group policy as a test and nothing seems to force the application to update unless a user enters the application and selects about.

Reading into how Firefox does this it doesn't seem viable to enable an auto-update feature without specifying the version it needs to upgrade to, we can currently patch to specific versions using SCCM.

Is anyone aware of a solution to this problem or another method?

Looked into calling updater.exe and the maintenance service but nothing i successful when trying to call on these.

Hello, from Terminal Servers, it is not possible to browse the Internet via FortiGate's explicit proxy from the Firefox browser, while there is no problem with Chrome or Edge. When the user tries to browse external sites, the proxy sends the error page "You need to authenticate to use this service". It seems that Firefox does not pass user authentication to FortiGate. The proxy authenticates users per session via Kerberos tickets.

Firefox version: 115.5.0esr

I also performed the following settings to pass the Kerberos ticket to the proxy without success: https://people.redhat.com/mikeb/negotiate/

I also noticed that it is not possible to change the "network.negotiate-auth.allow-proxies" setting from "false" to "true." Is this my problem? Is it normal that it cannot be changed?

Attached are the settings.

Thank you in advance.

Good day.

I have created a custom Search Engine via a GPO.

The search engine is added to Firefox without issue. However, when a user enters in a search with a space, Firefox replaces the space with a "plus" instead of a %20. The search engine does not know how to interpret a "plus," so the search engine returns 'no results found.' I use the same search string in a Chrome GPO, and it works as Chrome replaces a space with a %20. Is there a way I can tweak the Search engine GPO to use %20 instead of a "plus" for a space?

Thanks.

I am writing from an enterprise environment and I have been directed to the community page by Mozilla support to seek answers. This approach seems somewhat unreasonable for an enterprise setting and it has led me to consider discontinuing their product within our organization. I had requested support to send me a copy of my previous correspondence as I had forgotten some details, but this request was ignored, which is disappointing.

I am skeptical about receiving the help or answers I need here. If there is a more direct line to Mozilla support, I would greatly appreciate being redirected there.

We are currently using Firefox 121.0 and are attempting to implement the Applied Epic extension. I have updated the ADMX policy.

Originally, the reg key flip I created did work but something has changed since then. See screenshot of this. I followed the guide provided at https://github.com/mozilla/policy-templates/blob/v5.5/docs/index.md, which instructed me to place the registry key in Software\Policies\Mozilla\Firefox\Extensions\Install\1. However, the guide did not specify whether this should be in HKLM or HKCU. I tried this instead, and it did not work.

I also attempted to implement the extension via GPO, but this was unsuccessful. I tried the new Extension Management system as well, but to no avail.

Here is the JSON configuration I used: {

 "AppliedEpicExtension@gmail.com": {
   "installation_mode": "force_installed",
   "install_url": "https://addons.mozilla.org/firefox/downloads/file/4143256/applied_epic_extension-3.16.3.xpi"
 }

}

Despite following the guide and trying multiple methods, none of the options seem to work. I would appreciate any guidance on what I might be doing wrong.

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!

Hello,

I am trying to create a management policy for extensions where all themes are allowed, some extensions are force installed, other specified ones are allowed, and anything else is blocked. I have been scouring the web looking for samples and I just can't get it to work as intended. Here is a sample of what I have written.

{ "*": { "blocked_install_message": "IT has blocked the installation of UNAPPROVED add-ons. Please contact the IT Service Desk to request approval.", "install_sources": "https://addons.mozilla.org/*", "allowed_types": ["theme","extension"] }, "plugin@okta.com": { "installation_mode": "force_installed", "install_url": "https://addons.mozilla.org/firefox/downloads/file/3601147/okta_browser_plugin.xpi" }, "support@lastpass.com": { "installation_mode": "force_installed", "install_url": "https://addons.mozilla.org/firefox/downloads/latest/lastpass-password-manager/latest.xpi" }, "developer@zoom.us": { "installation_mode": "allowed", "install_url": "https://addons.mozilla.org/firefox/downloads/file/4212428/zoom_new_scheduler-2.1.52.xpi" }, "info@katalon.com": { "installation_mode": "allowed", "install_url": "https://addons.mozilla.org/firefox/downloads/file/3826743/katalon_automation_record-5.5.3.xpi" } }

In this current state, I am allowed to install themes, I get the forced installs, but I can install ANY extension. I don't want that.

If I modify the blocking section with [ "installation_mode": "blocked", ], then I only get the force installed plugins and I can't do anything else. It even removes any previously installed themes or plugins not explicitly forced in. The allowed plugins can't be installed either.

I have also tried it without the "extensions" allowed_type but the result did not change. To recap, I need to block any extensions not explicitly pushed or allowed. Would anyone be able to assist and point out what I may be missing please?

~Regards

Good afternoon,

We're currently trying to set up a Hardening Guide for Firefox ESR but are struggling with a few policies and setting wildcards.

For example, we're trying to set an origin in Cookies > Block Settings to something like "*", and we get the error "Ignoring parameter "*" - not a valid origin."

In Chrome / Edge you can set a wildcard like this: [*.]google.com for example - we receive the same error message for this.

Can you do such a thing for Firefox ESR without having to list every site you want to block?

ESR Version: 115.6.0esr (64-bit)

Software used: Firefox ESR 102.15.1 on RedHat Enterprise Linux 8 with the Xfce4 desktop environment in version 4.16.3.

I run two Firefox windows on two different virtual desktops. Most open tabs in each of them are tied to the workflow I use on each desktop, in case this is somehow important.

Problem description: Sometimes, Ctrl+clicking on HTTP or HTTPS links will open the resource in a new window instead of in a new tab. This appears to be random, and does not depend on the link target. It is also not properly reproducible, so the same link may work just fine and open the resource in a new tab as expected on another attempt to Ctrl+click it.

Properties like browser.link.open_newwindow or browser.link.open_newwindow.override.external are unmodified and set at their default values.

I can drag the new window's only tab back into the browser window in which I originally clicked on such a link, but this is becoming tedious. Sometimes I overlook this, resulting in a chaos of multiple open Firefox windows with multiple open tabs in each of them.

The behavior I would expect: When Ctrl+clicking on links, their resources should always open in a new tab, never in a new window, unless it's a link with a protocol that Firefox by itself won't handle and where it will have to rely on another program to open it (e.g. ftp://, ssh:// or mailto:somebody@somedomain.com).

My request: I would like this to be fixed if it's a real bug. If I am somehow responsible myself without knowing why, please just let me know what I might be doing wrong.

If there are some workarounds for this, e.g. some properties I could set in about:config, help with those would be appreciated as well.

Most information I can find about similar problems is pretty old by now and pre-dates Firefox 102.15.1 by many releases and years. All suggestions I could find about what one would need to change in about:config to fix this seem to be the default by now anyway.

Thank you very much!

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.
