Then if you need to change something, you need to change those individally per platform.
With this you can set it up and centrally manage them from a single dashboard, the only thing you need to do is to do the platform-specific enrollment once.
I'm glad Mozilla is trying to find a way to monetize the platform in exchange of providing a tool to better manage the browser at the enterprise level.
Firefox Enterprise tries to remove as much friction there as possible, and adds a pile of features like deployment monitoring, policy changes while running, device posture checks, various security features like SIEM logging, etc.
The other part is that you get the option to run all supporting services entirely on premise, so the browser never has to "phone home" to us, but you still have working updates, sync support, and so on.
