Users have XP, Win 7 OS. Deployed a GPO for Trusted Root Certification Authorities for IE and was successfull. Not hte case for Firefox on the same machines. If I view the local Firefox certificates, my deployed cert does not show up. We are in a domain environment with Win Server 2008 R2. Is there a way to deploy the same certificate for firefox?

I am not an expert, but this may put you in the right direction for those who have done this before, if you have trouble please do let us know.

I found some recommendations here: Barracuda " FirefoxADM for allowing centrally managed locked and/or default settings in Firefox via Group Policy Templates in Active Directory. More information is available at"

and "SSL Certificates: Setting Up and Authorizing the Internal Certificate Authority "

Hey all, I asked about this in the #security irc channel and there were a few recommendations:

If you publish a webpage that has a link to the certificate that they want the user to trust

<a href=''>

mime type


Then when the user clicks that link, the user will be given the option of trusting the certificate.


What do you think?

Publishing the webpage may be the way to go, I will definately give that a shot. I will post back when I get the results, thanks!
