Playing devil's advocate, many firefox extensions don't work as well or at all as they used to. tree style tabs can't integrate in the same way without extra modification, all of the FF extensions that allowed you to control your browser with vim bindings no longer work. I actually still think the API design was a good idea and am glad for the added security. Still, the API change took down some popular extensions for sure.
