Disable Create New Profile
Can you add a configuration setting to Mozilla Firefox to disable Create New Profile, configurable in the policies.json file? (A second option but a much uglier one would be to disable being able to select a file location for a new profile. Then you could make the default profile directory write only, which would also accomplish the same thing.) (A third option would be to able to configure extensions by default upon installation in the ExtensionSettings policy.)
To explain, I use LeechblockNG on Firefox on Ubuntu. Very helpful. By placing a policies.json file (see at bottom) in /etc/firefox/policies/ directory, I can create a system wide policy. I can make the LeechblockNG extension mandatory and to be installed upon every new profile creation. That all works very well. HOWEVER, there is NO way to be able to set those options in the new profile. So LeechblockNG is installed with default options (which are no blocking at all), which effectively bypasses the addon.
I am also writing the author of the leechblock extension to see if there is any way to set the options for leechblock upon installation (the third option above).
But I know other people have this same question, and at present, if I am correct, there is no way to block new profile creation, or the Profile Manager window in Firefox.
So could you please add that option to the Firefox policies.json configuration? Something like "DisableNewProfiles": true would do it.
Thanks!
My current policies.json file in /etc/firefox/policies/ directory: { "policies": { "BlockAboutConfig": true, "BlockAboutProfiles": true, "PrivateBrowsingModeAvailability": 1, "DisableSafeMode": true, "ExtensionSettings":{ "*": { "installation_mode": "blocked", "blocked_install_message": "Prohibited install more extensions." }, "leechblockng@proginosko.com": { "installation_mode": "force_installed", "install_url": "https://addons.mozilla.org/firefox/downloads/file/4374316/leechblock_ng-1.6.6.xpi" } } } }

Note that you normally do not specify a specific extension version, but use a link the get the latest version, you need the ID of the extension. See install_url:
Thanks for the note. But that still doesn't solve my problem. I note that Google Chrome does have such an option, but Firefox does not. On Google Chrome, the policy option is called: BrowserAddPersonEnabled There are also other helpful policies on Google Chrome like: BrowserGuestModeEnabled. But the BrowserAddPersonEnabled would be the one I would love to see on Firefox.
I asked the author of LeechblockNG, and he suggested either:
1. Making the profile directory write-only (but there is an easy to bypass this, just select a different directory to put the profile in). 2. Forking the LeechblockNG code to start with the proper settings. (Not a great option, complicated, and misses future updates.)
I'm thinking of switching to a different browser unless I hear back on this subject. LeechblockNG is available on Chrome and it does have the BrowserAddPersonEnabled policy option. So that's probably where I will go. Too bad. But I'll wait for a reply first.
I would love to be able to restrict Create New Profile to administrators only, but I don't know how. There is no configuration option in Mozilla Firefox currently, to my knowledge. That is precisely my question. I am using Mozilla Firefox on Ubuntu. If you want more details, I would be happy to share them. Thanks for the answer!
To disable the "Create New Profile" option, follow these steps based on your system or platform:
For Software Applications:
Check the settings or permissions section within the application. Look for options to restrict profile creation and disable it. For Websites:
Adjust the admin or backend settings. Disable the feature under user management or account settings. For Enterprise Systems:
Use role-based access control to limit permissions. Restrict the feature to admins only. If these options aren't available, refer to the platform's documentation or contact support.
So I guess there is no way this option will be added to Firefox? I think that means I'm moving to Chrome, sorry! Chrome has that option; it's a shame that Firefox (which copies the json configuration) can't add a similar configuration option like Chrome has: DisableNewProfiles.
