Neither of those is a good choice. The custom Firefox-only would be a waste of developer resources. Similarly, picking a winner is also a waste of developer resources: there were already extensions that had far more functionality. Firefox should have added a more general "Experience Enhancements" feature that suggested great features that could be enabled and offered a few options. This same concept of periodically offering enhancements to users could be presented periodically and offer any number of things over time. My complaint is the Mozilla folks missed a more general, better capability they could have built.
