Firefox for Enterprise Support Forum

I have been trying to automate setting a homepage for my users. I have tried a number of ways including a script I found but changing the prefs.js on my account doesn't seem to affect Firefox at all. I can append "browser.startup.homepage" in the view:config if I open Firefox locally and that seems to change the homepage as intended but putting it into a script doesn't seem to do anything unfortunately.

I have also tried what's recommended in this guide however that did not help either.

https://smallbusiness.chron.com/change-default-homepage-users-54727.html

Is there a way to do this through regedit or group policy? Preferably a way that still allows the users to change the homepage if they like.

Background information: since version 87 of firefox, I have been having problems viewing pdfs online. All the suggestions from people provided on the post, placed in another part of thecommunity, didn't work for me. I decided to remove my installation of Firefox and install a new uptodate version. I decided on this after I had installed Brave as an alternate browser and changed it to the default browser in my frustration. Now: I was unaware that I had downloaded the enterprise version. When I got to the settings, next to "make Firefox your default browser" there was a statement in red saying "your browser is being managed by your organization". Clicking the link brings up a policy screen which says "don't check default browser" with a value of true and no way - as far as i can see of changing the value. And it is also unchangeable in Brave. I hope someone has an answer for me. The one good thing about the current situation is that I can read pdfs in the browser. Is there an emoji for headache?

I am trying to package an add-on that I created with a custom installer for firefox nightly, but the add-on is not being automatically installed with the browser.

I followed the instructions at https://support.mozilla.org/en-US/kb/repackaging-windows-installer and at https://support.mozilla.org/en-US/kb/deploying-firefox-with-extensions, but to no avail.

Any help would be greatly appreciated.

I am trying to use a policies.json file to include a certificate for my own website using a certificate stored online, but not locally. Would it be possible to do so using code similar to below: {

   "policies": {
   "Certificates": {
       "ImportEnterpriseRoots": true,
       "Install" [
           "cert_name",
           "http://www.xxxxxxxx.com/xxxxx/xxxxx.der"
                  ]
            }
       }
   }

Any help would be greatly appreciated.

I am in an enterprise environment with over 500 machines, and we are looking for a way to import users Bookmarks from IE to Firefox silently and behind the scenes without requiring user interaction.

Due to security restrictions 3rd party software is not a possibility. Most users have already been using Firefox. We do not want to delete their existing bookmarks in Firefox

Does Firefox have, or plan on having, their browser updates available via SCCM Automatic Deployment Rules library? There are some non-Microsoft software vendors now allowing their software to be included in the SCCM Automatic Deployment Rules library for more efficient upgrade and distribution.

Good Morning,

In my organization some years ago I pushed to have Firefox as our default browser and finally was accepted. It has been very good as we have over 10K employees using it. However this last week there has been a new release that forces you to create a new profile, one that is achieved all of you original settings and data are gone. We are a health care organization and cannot have this. I sent the fix (about:profiles) to our triage support department. However once the old profile is chosen and made the default. It will revert back to the new one each time you restart or the next day. I need a permanent fix, is there a way to update the old profile to the new version of Firefox? Shouldnt it stay the default once you make it so? I am getting inundated with calls over this, please send the fix asap.

Today at 11:30 AM Just to be clear, you tried the about:profiles fix in the Recover user data missing after Firefox update article ... but it will revert back to a new profile at every restart? (YES) In any case, since you are using Firefox in an organizational environment I'll move this to the Enterprise forum. (WHERE IS THIS AND HOW DO I GET TO IT?)

Today at 11:47 AM P.S. See also https://support.mozilla.org/en-US/questions/1267878 New clear profile every time after Firefox update and Dedicated profiles per Firefox installation ... which refers to Downgrade protection and starting Firefox with the --allow-downgrade command line option, when you have multiple versions of Firefox installed. (DID THIS)

NEED SOME REAL HELP HERE, NOT JUST LINKS TO STUFF I ALREADY TRIED. I APPRECIATE THE REPLY BUT SINCE YOU CLOSED THE TICKET AND MOVED IT, I CANNOT FIND IT NOR CAN I REPLY TO YOU. I HAD TO OPE A BRAND NEW TICKET.

Background: The environment is a Windows 10 based peer to peer network with one PC acting as file and print server. The printer is a Xerox WorkCentre, shared via UNC path to the clients, connecting via fixed IP address (not WSD).

OS: Microsoft Windows 10 Pro, 64-bit (build 19043) Mozilla: Mozilla Firefox ESR (x64 en-US) 78.12.0

• On this network the Xerox is defaulted to A4 paper and all PC's pull these settings from the print server.
• The local PC settings also show default paper size as A4.
• Most programs (Word, Outlook, Notepad, Print Test Page) respect these settings and so when printing, the print job prints as expected.
• Firefox will print non-PDF pages to A4 as expected.

* PDF files, when opened in Firefox, do not print without causing a paper sizing related error on the printer.

• In turns out the when querying the advanced settings, the Firefox PDF engine is defaulting to Letter paper.

So there are two issues as I see it:

1 - The Firefox PDF engine is not respecting the default paper size of the default printer. 2 - There is no way I can see to tell Firefox to use A4 paper.

As a side note none of the printers have a locally installed printer, I have no idea if this makes a difference.

My workaround has been to install Adobe Reader and set this as the default PDF reader both in Windows and Firefox.

Does anyone know how to set Firefox to A4 for it's PDF engine?

Since Firefox allows users to install to individual profiles, how do admins go about uninstalling it for all users silently and remotely? If all 1000 PCs have 50 users, all with Firefox installed to individual profiles, I can't imagine IT admins would have to find the appdata for each and every user and modify a script for each machine and every user. There must be a simpler way, right? An "Uninstall All" for Firefox?

Hello,

We use FireFox MSI file to push out to all my users that I have on my Azure Domain. But constantly I find myself having to download new MSI packages monthly in order for our users to keep there profile intact and to update there Firefox. If I do not do this, users profiles they have on their PC will be wiped cleaned and they will have to start over new and then manually update FireFox. Only to have there dreams crushed when Azure pushes out the older version of FireFox the next day when they attempt to sign-in and sync with the domain.

Is there a way to prevent this manual process from me of uploading new MSI files monthly in order for our users to use FireFox with no issue? Strong pain point for any of my users that prefer to use FireFox, but Google Chrome and Edge does not have this issue.

Dear Madam or Sir,

there seem to be new performance settings to be available since Firefox 91: https://support.mozilla.org/en-US/kb/performance-settings

While I have been able to "Use hardware acceleration when available" by using ...

{

 "policies": {
   "HardwareAcceleration": false
 }

}

... I could not find any setting to disable "Use recommended performance settings". Is there any possible way to disable this feature in dsitribution/policies.json ?

Thank you very much in advance!

Best regards

Victor

Is there a solution to preinstall user specific bookmarks? After new installation of Firefox, the profile folder does not exist and i can not copy places.sqlite into it. If i use policies.json there are only systemwide bookmarks possible. But i am looking for user specific bookmarks to deploy after a new installation.

Hi, is there an option to customize the Firefox installation in a way that would be Pre-configured with bookmarks in the created profile? we have about 50 workstations and it would be pretty tedious and inefficient.

Hi, I'm trying to create a Windows GPO to control Addons/Extensions in our FireFox installations.

From the doc I've read, the place is Policies|Administrative Templates|Mozilla|Firefox|Extensions Policy is "Extension Management"

I set it to enabled and include this text: {

 "*": {
   "blocked_install_message": "My Custom Test Message",
   "installation_mode": "blocked"
 }

}

When I hit apply, I get this error message: "No text was entered for this field. Make sure that you enter text."

If I put nothing (but still enabled) or "A" or A, then it accepts that. It's when I plop in the JSON that it fails.

What am I doing wrong?

I have ESR 91.0.1 and policy 3.0 installed. I do not have Firefox installed on the machine doing the GPO work, that's currently only on the test machine. I do have the policy definitions installed.

-g

I am using group policy, extension settings. I want to block all extensions, require 1, and allow a handful. I think I have the JSON figured out but finding the URL to use is escaping me.

I can find the site in the Mozilla addons, https://addons.mozilla.org/en-US/firefox/addon, but how do I find the exact filename to use? I see that many end in latest.xpi but I'm unsure what that means or how I should know which is correct. I know how to find it in Chrome but I'm now trying for FireFox. I've had a hard time and it's not as clear as the direct GPO implementation as Chrome uses.

My next thing to figure out is when extension settings are mentioned in multiple levels of the GPO hierarchy. That's a separate question and not needed for an answer to this question. I only mention it as someone who knows one part is likely to know the other as well.

Thanks, -g

I am currently creating new Images for our touch kiosks and would like to use Firefox.

Sadly I am confronted with some problems / strange behaviour.

I want to set up a windows Kiosk with Firefox as shell application. So far this worked but the Firefox window opens around 5 times at every restart, also it does not open again if it is closed. The reopening is a feature of the eshell which reacts to the exit code of the Application. Is there anything you know what causes these behaviours? Google chrome does nothing of these things and simply gets restarted if it is closed, as it should.

The second thing is, the built in Kiosk mode is great but our Application at least needs tabs. Is it possible without too much of a hassle to create such a locked down experience? I'd like to do it with a policy or settings file and not to create my own browser out of firefox, maybe there's a way I have overseeen.

I'd really like to do it with firefox as I personally always had a great experience and I trust the team behind it. Thank you for your support beforehand!
