Firefox za Enterprise Forum podrške

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!

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.

Hi,

We've GPOs in place for Edge and Chrome that set said browsers on all our Windows endpoints to open downloaded ICA files in Citrix Workspace.

I've imported the firefox.admx and mozilla.admx file along with assocaited .adml files, checked Github, checked through the GPO settings yet cannot figure out how to do the same with Firefox.

Is there a Mozila Firefox for Windows GPO ADMX setting I can use to control the "Firefox>Settings>General>Files and Applications>Applications" section to add "Content type: ica | Action: Use Citrix Workspace"?

Thanking you....

We downloaded the GPO Templates for AD and looking to customize Firefox.

We would like to disable Forms and Autofill: Autofill addresses Autofill credit cards

Also would like to lock down so they can't reenable if possible.

We would like to do this all through GPOs if possible. I found these in the about:config: extensions.formautofill.addresses.enabled extensions.formautofill.creditCards.enabled

But again want to do through the GPO. Is this possible?

Side note while working on GPOs, I set Exceptions for the popup blocker and they are not showing up in the browser. I also filled out to remove Search Engines but they all still appear in the browsers. These two GPO settings don't appear to be working.

I am an admin of some servers, i modify the proxy settings of firefox in a GPO, and it works, but now ont thing is that users can modify the settings of "No proxy for" in Connection Settings, then add the urls, then users can access to any web site which they want to, is there a method to disable this? thanks.

Hello, Qualys is detecting Vulnerabilites on our Firefox ESR 91.12 Versions which were patched by MFSA2022-29.

It is showing Vulnerabilities because MFSA2022-30 lists CVE's for ESR 102.X and we are on 91.12.

Is there anywhere I can go to get a list of all Vulnerabilities on 91.X to show our Security team, I believe CVE-2022-36314 and CVE-2022-2505 are not present in 91.12 because they are not listed in https://www.mozilla.org/en-US/security/advisories/mfsa2022-29/ but need evidence

Thank You,

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.

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.

Hello, ever since we moved endpoints from Firefox ESR 91.13 to 102.3, it has become impossible to play any media with Firefox.

No video will play in youtube, for instance (it just loads endlessly as if it would start, but it doesn't).

Can't use radio websites either. Anything with a "play" button (video or sound) does nothing.

This has been tested with a clean profile, a clean install, after allowing autoplay in the settings.

Is there any info on what exactly changed between ESR 91 and 102 that might explain this ? There has been no system change, If I reinstall 91 instead it works again as usual.

No issues anywhere else on the endpoints (Edge, Windows), this is on Windows 10 if it makes any difference.

Tanks for any help on this.
