We have put user and computer startup scripts to detect and delete firefox from our enterprise customers. Firefox cannot be kept SAFe through InfoSec. InfoSec and SAFe require the business be in charge of security which is what our customers understand. They constantly find firefox out of date and vulnerable. We have tried over and over to use the firefox admx files to force background update both at the computer and user OUs but find that users can uncheck the box and it remains vulnerable and out of compliance. Edge and Chrome can be controlled by the business (not end user) through group policy and kept up to date and we never find either out of date by implementing our policies. Firefox constantly tells end users how to check the boxes and no group policy can enforce them as we don't see the registry updated even though we even put a registry patch in, firefox is still in the control of the end user and not SAFe. If you don't know what I mean by SAFe, check this out. https://www.scaledagileframework.com/devops/
