Firefox for Enterprise Community Forum

Hi,

In the latest firefox update 149, no start pages are displayed that were distributed with a registry key via group policy. It only works again if you change this setting manually in the Firefox settings.

In Version 148 it´s fine.

Hello community :)

hope everybody is doing well. I´m coming here with with asking for a help.

I´m managing browsers (Google Chrome, MS Edge and Firefox) in my company via GPOs. What we´ve been dealing with since 135 version came up is having the "Did Not Connect: Potential Security Issue error page , Error insufficient cert transparency" while visiting our internal resources.

Despite of having the security.pki.certificate_transparency.disable_for_spki_hashes set up -> main three certificate hashes are correctly added, basically copying the setup from Chromium browsers , where everything works as expected , Firefox is not.

The only way how to make it work is via security.pki.certificate_transparency.disable_for_hosts , which is , of course, not desirable , because of the security risks.

Does anyone face the same issues ?

Thank you very much ya´ll

Hi All, I want to block traffic on firefox externally for managed devices via Intune, following the import of the ADMX/ADML files into intune.

I have set '\Mozilla\Firefox\Exceptions to blocked websites' to the following

• //*.mydomain.com/*

which works, however, I also want to add hosts that are only resolving on IPs and not DNS. I can add specific IPs if known, but is there a way I can allow IP ranges? Ie

• //10.10.*/* (this doesn't currently work)

Of the included screenshot, only the wildcard for mydomain.com and the specific IP currently work

If there is a better way to do this via intune for firefox only, please let me know.

Thanks

Is there any parameter or group policy similar to Chrome "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome\AutoSelectCertificateForUrls]", as we implemented application with Certificate sign-in, it pop-up every time when navigating to different on-prem servers, we enabled Group policy for MSEdge & Chrome, but need to do same for Mozilla Firefox.

I need expert advice on this subject matter.
