Hi all,

we are using Firefox for more than 5000 users in our corporating. We deliver Firefox via SCCM packages to clients and include a config file for setting a few (fix) settings for all users. We do not use GPO (Group Policies) for Firefox.

Now our issue: we want to have a initial state, so that Ecosia becomes default search engine (changeable). There were a lot of different parameters for about:config (and cfg-File) for setting an initial or fix search engine (such as browser.search.defaultenginename), but all of them are deprecated (due to maleware/adware issues?).

All I find now is the parameter named browser.search.searchEnginesUR, but it only retrieves a central URL with a list of search engines.

So I thought about these possible solutions: - Finding an other parameter to control the default search engine (or Addon, or GPO,...) - or: Creating an own (hosted) search engines list with Ecosia on top level (first entry).


Thank you so much in advance! Best Regards, Yannick Wickum

Hello,

in our environment we have different Citrix PVS Images and would like to use the same gpo for firefox for all Images.

As we live in a multilingual country, we need to distribute german and italian languagepacks for firefox. We used the firefox.cfg with the following settings to achive this goal:

lockPref("extensions.blocklist.enabled", false); lockPref("extensions.autoDisableScopes", 0); lockPref("intl.locale.requested", "");

XPI Files where copied to C:\Program Files\Mozilla Firefox\browser\extensions\sample.xpi

With the release of Firefox 73.0, sideloading is no longer possible. Adding the extension trough GPO "Extensions to Install" https://addons.mozilla.org/firefox/downloads/file/3541579/italiano_it_language_pack-75.0buildid20200403170909-fx.xpi is not the way i would like to achive this.

Documentation (https://github.com/mozilla/policy-templates#extensionsettings) isn't exactly clear how to add an extension from a local source. GPO Setting would be Software\Policies\Mozilla\Firefox\Extensions\Install\2 = "C:\Program Files\Mozilla Firefox\browser\extensions\langpack-de@firefox.mozilla.org.xpi"

Hence I am adding another key-value pair under this- Software\Policies\Mozilla\Firefox\Extensions\Uninstall\1 = "addon_id" I am getting the addon_id by clicking on debug addons, from the list I copy the extension id of my addon. ( I am assuming this is what is meant by addon id). But no matter how many times I try this, on different machines, different addons it's not working. The addon doesn't et uninstalled.

Hi, after many days spent to find out how to get my unsigned add-on to work, I'm able to run it only once after first installation.

Here is what I did: https://support.mozilla.org/en-US/questions/1273813

Add-on works either in debug mode, loaded from file and installed via policies.json until I close browser. Next time I run FF my add-on is not invoked at all.

manifest.json file contains this directive:

 "browser_specific_settings": {
   "gecko": {
     "id": "myaddon@domain.local"
   }
 }

Probably I miss something, but I did not find it in documentation. Any help will be appreciated Thanks in advance


I found how to view browser activity during restart, you can view it here: https://pastebin.com/pB2qBpR2 Thanks

I think that sample is supposed to block all but 1 firefox extension, but it's still letting me install any extension. For this feature, I'm running Firefox 70.0 64-bit on Windows 10 How do I properly configure the group policy so that only approved extensions are allowed?

Hello. I have installed an add-on using a GPO. However, after upgrading to Firefox 68, my add-on is getting an installation error. Is it impossible to install by GPO on Firefox 68? If not, why is not it installed?

I attached the part that I confirmed by connecting to about: policies. Installation via download, not GPO, is installed normally, below is the installation link. https://addons.mozilla.org/firefox/downloads/file/3365031/gradius-7.3.11-fx.xpi?src=devhub

In the case of GPO installation, my add-on as well as other add-ons are not installed.

Please check the issue. Thank you.

Failing to consistently set default search engine for Firefox ESR 68.1 using Group Policy Objects (GPO)

Hello !

I'm trying to create a GPO that would set the default search engine of Firefox ESR 68.1 to Qwant by using the Default Search Engine policy. My problem is after the initial installation, if I change manually the search engine in the options (about:preferences) for some other search engine (Bing for instance) it does not revert to Qwant when I run the gpupdate /force command to apply my GPO once more. Is this an expected behaviour ?

I have also observed, while Qwant is the default engine, that if I edit my GPO and set the Default Search Engine policy to Bing the search engine will change to Bing on Firefox when I apply the GPO (using the same command as before : gpupdate /force), and if I change it again to Qwant in the GPO and apply it, Qwant will be set as the default search engine for Firefox.

Therefore I don't understand why as long as I don't modify the GPO the Default Search Engine policy don't seem to be applied even when using the /force in the command line (which is supposed to apply all the parameters if I am not mistaken).

Other informations : - The default search engine is, as expected, set to Qwant when I install Firefox and there is no profile - The default search engine reverts to Qwant when I use the Refresh Firefox button in the Troubleshouting Information

I hope I was clear in my explanations and thanks those who will answer to my post ! :)

I am looking for a preference setting in one of the configuration files, preferably user.js, to tell Firefox to open pdf files using "Adobe acrobat (default)" rather than the built in viewer. I can do it through the user interface, but I need to push the setting to multiple users. I noticed that when I manually change the setting, pdfjs.enabledCache.state is changed from true to false. But that does not seem to be the only setting that changes.

Good afternoon Community,

I am a (very new) enterprise admin for a very large organization. We have decided to start distributing Firefox (Quantum Version 68.0 32 bit) across our organization. We utilize a smart card application for logon, and user website authentication. We have every setting exactly how we want it, save one. Each individual user, for each profile they create, will need to upload the .DLL file from our smartcard reader application to the security devices. If this were just a hundred or so users, that would be easy, but we are in the thousands (and more.....). And many of these users are not technically savvy. Is there a way to have a specific library uploaded as a part of building the profile? Sort of like a pre-built default profile. Ideally, we would like to do this with no additional extensions or plugins installed.

Hi, using the latest FireFox ESR I cannot get this customization to work. The error is "Failed to read the configuration file"

The file is:

// disable default browser check pref("browser.shell.checkDefaultBrowser", false); pref("browser.startup.homepage_override.mstone”, “ignore”);

// clear cookies pref("privacy.clearOnShutdown.cookies", true)

This has worked before, using the local-settings.js this file is:

pref("general.config.obscure_value", 0); pref("general.config.filename", "mozilla.cfg");

Any ideas?

Hi,

I'm trying to manage Firefox on 75 Macs. I need cookies to be enabled, not cleared on Firefox shutdown with third party cookies accepted. Nothing I have tried in my mozilla.cfg file is working. Either one option is set or another, but not both. Here's my mozilla.cfg file:

// set Firefox Default homepage pref("browser.startup.homepage","https://www.google.com"); // disable default browser check pref("browser.shell.checkDefaultBrowser", false); // disable application updates pref("app.update.enabled", false) // disables the 'know your rights' button from displaying on first run pref("browser.rights.3.shown", true); // disables the request to send performance data from displaying pref("toolkit.telemetry.prompted", 2); pref("toolkit.telemetry.rejected", true); // enable cookies system-wide pref("network.cookie.cookieBehavior", 1); // do not clear cookies on shutdown // pref("privacy.clearOnShutdown.cookies", false); // accept third party cookies pref("network.cookie.thirdparty.sessionOnly", false);

What part of the above is wrong? OS is macOS 10.13.6 "High Sierra", Firefox is version 61.0.2 "Firefox Quantum."

The whole reason for this is to satisfy a cookie requirements for a site we regularly use.
