Hello. I just wanted to add 8-10px border-radius and a thin 1px border. Just like all chromium browsers already have and even Waterfox did it too. I tried to do different things already, but I couldn't find the way how to get rid of that background with square corners. See the attached image to better understand what I mean. My attempt on the left, and Chrome on the right. These square corners (green in this case) behind. Any ideas? Thanks in advance for any answer.

Im working on a deployment package for Mozilla Firefox 106.0.1 when launching Firefox on a brand new user it automatically creates a shortuct for private browsing. Im looking for a way to disable this as the package im creating is an appv package and this new shortcut installs in users profile, so it won't be uninstalled. I have searched google but cant find any hits.

We have the following for customization: Application directory\defaults\pref: localsettings.js with these settings: pref("general.config.obscure_value", 0); // only needed if you do not want to obscure the content with ROT-13 pref("general.config.filename", "mozilla.cfg");

Application directory\mozilla.cfg with these settings: // Don't show WhatsNew on first run after every update pref("browser.startup.homepage_override.mstone","ignore");

// Don't show 'know your rights' on first run pref("browser.rights.3.shown", true);

// Disable Policy Notice on First Run pref("toolkit.telemetry.reportingpolicy.firstRun", false);

// Disable checkDefaultBrowser lockPref("browser.shell.checkDefaultBrowser", false);

Application directory\distribution\policies.json with the following settings: {

 "policies": {
   "DisableAppUpdate": true,

"DontCheckDefaultBrowser": true } }

We have configured Windows Single Sign On to Microsoft 365 in Firefox 102.6.0esr (64-Bit).

We have embedded a Video from the new Microsoft Stream on SharePoint Online into a SharePoint 2019 onpremise Site via the provided iFrame. Here every user gets an endless Login Loop (see Screenshot).

If you open the deeplink to the video, Single Sign On works perfectly.

And this also works in Microsoft Edge, why the Microsoft support is not willing to analyse this issue further.

Do you have any ideas how to narrow down the problem?

Hello, I am trying to manage Firefox Extension using "Extension Setting" via Intune. Source: https://github.com/mozilla/policy-templates/blob/master/README.md#extensionsettings I am testing below JSON for testing. <enabled/> <data id="ExtensionSettings" value=' {

   "install_sources": ["https://www.example.com/*"],

   "installation_mode": "allowed",
   "install_url": "https://prod.extensions.dashlane.com/downloads/firefox/dashlane-latest-fx.xpi"
 }

}'/>


When deployed to test devices, all extension previously installed get removed and Ublock get installed, seem like working as intended but when I try to install any "Allowed" I get the block installed message. I see no error in "about:policies". I don't know where else to look for why its getting blocked?

Any help will be much appreciated.

One of our vendors websites does not load under Firefox ESR, with errors in the console pointing to CSP. Error is: Content Security Policy: The page's settings blocked the loading of a resource at inline ("default-src")

However if I load the site under the normal Firefox release, it displays correctly. When looking at errors in console, it is showing 3 errors for CSP, however it does not stop the site from working correctly. Content-Security-Policy: The page's settings blocked the loading of a resources at https://..... ("connect-src") or ("img-src")

The site is https://app.approvalmax.com If you get the login screen then the site is working otherwise just getting a green background when it is not working.

I am unsure why ESR and RR versions are behaving differently in this case. Using the latest versions of each.

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!

We have Firefox rapid-release (not ESR) deployed on Windows 10 across our Enterprise where users do not have local Administrator privileges.

Occasionally the rapid-release updates fail to be installed, with the updater requiring Admin privileges to execute. For example, today a user's Firefox 111.0.1 was asking for elevate to update to 112.0.

The IT team user accounts also are non-admin, but we have not run into this, and judging from the lack of support tickets on this I would say most of our users are not running into this either.

Does anyone have any suggestions on how to avoid this, or troubleshoot further?

I work for the local County and we recently got a new content provider that allows for SSL Inspection (Barracuda 410) but it requires a certificate to be installed on every device to work. I am aware of Edge having a way to create a custom installer that would allow us to preinstall the proper certificate, but was wondering if Firefox had the same thing. I am also needing to know that if we push out the version of Firefox with the certificate preinstalled, would it auto import our user's data from their current install of standard Firefox?

Hi,

i'm running Firefox on +70 Windows 10 PCs in three labs in a university. I've applied a computer configuration GPO with AppAutoUpdate enabled, BackgroundAppUpdate enabled and DisableAppUpdate disabled to my PCs, but it looks like i don't get automatic updates. In my labs i see some workstations have Firefox 108.0.1, but most workstations still have Firefox 107.0.1...

As my users can switch between workstations and labs, this leads to the annoying 'older version' message box when a user worked on a PC which already got the update and later uses another PC which didn't get the update. The users are also forced to create a 'new' profile then, which is quite problematic because of the size of the roaming profiles.

Any hints?

I have tried the obvious and removed the {} from both extensions, however still having troubles.

Is someone able to point me in the right direction?

I am using the intune preview feature which allows you to import admx/adml instead of using the custom injection method. Everything works far better then with the injection method, except for one settings:

ExtensionSettings this setting is working when I have only one setting set (ex):

{"someplugin@test.com": { "installation_mode" : "allowed" }}

If I add a second line to the entry:

{"someotherplugin@test.com":{ "installation_mode" : "allowed"}}

I understand this is a new feature, but if I had the correct format that would work for HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox\ExtensionSettings to allow two plugins to work I belive I shouldn't have any issue getting the admx feature to do this, I even tried manually editing the registry setting and it breaks whenever I add the second line to it.
