Thank you! We have a dedicated Firefox Enteprise team that is in my org (New Products) rather than the Firefox org precisely because we want to make sure it can be properly proritized.
However, I would also venture that prioritizing "power-user" requests may end up helping your enterprise product, given the overlap between IT teams and power users. There is a lot of functionality that was lost in the interests of simplification. Even some of the appearance - such as the awful "let's add bouncy curves to every UI element" in your latest rollout - can have a very solid impact on how people perceive your product. Enterprise is a different sensibility than average user.
